It has 5 legs

In the first pic it appears to have five legs. To my eyes,the wood seems to be too fine-grained to be oak, but it certainly could be . A pic of the table top might help in identifying the wood. I agree with the 1900-1920 era. You may want to try a Google search and look at antique tables on eBay to give you some clues as to age, value, etc.

I believe it's oak....because those tables that looked like that were. I didn't see the 5 legs, but that's the usual thing. The extra leg supports the center when the table is opened. Looks like yours is missing the sliders that allow it to open.

looks funny w/o its casters.

Here is a photo of the top. I will look more on Google and ebay. I do have a leaf in it, but it is not the original one. My mother in law never had the original leaf and I have never seen it with casters on. It does have holes in the leg for them.

woodrose is right, not oak. Regardless, it can finish up nice and you will have a beautiful table.

I disagree....it's oak but with out a large figure,,,,but no matter what you call it, it is still the same table.
I am sorry that the slider mechanism has been removed and the casters lost. Those make the table a better height for getting your knees under. perhaps you can find replacements>
there were many many of those tables made by many different makers, you won't find a maker's mark. As said, dated to about 1900 and a bit. As is, missing the slider mechanism and without casters, you might get $100 for it if you were to sell it.

I'm confused doesn't the slider mechanism allow you to open the table so you can put a leaf in it? If so I can open it I just don't have the original leaf.

Its magical unicorn oak that happens to have the color and grain of maple. Sure Linda.

Wow.....you must be smokin' somethin' because I sure never saw maple with a grain that open....but then, of course....you are the "pro".

I'm not sure what a "pro" is on these forums. I don't make a living buying and selling antiques.
But my father's hobby was refinishing antiques, my grandfather was a carpenter, and another grandfather was a cabinet maker who worked with fine woods.
I have been buying refinishing and occasionally selling antiques for a little more than 50 years, and I have learned from many "pros" during that time.
A great deal of what goes into the analysis of what kind of wood is in a piece, is knowing when that piece was made and what woods were used at that time for that style of furniture.
Nope...I'm not a "pro"...never made more than a few hundred from buying and selling, but I have spent a lifetime studying and learning.

Common real antique furnitures are made with more than one type of wood. This table is an American or a Canadian made, late Victorian, probably walnut mixed with another hardwood, and for sure between 1850 to 1890. I am not 100% positive about the rectangular top (if it is the original one... maybe), and standing on five round reeded legs. The tip of the legs were cut, normally they finish on a smaller pointy style. The original colour should be a brown reddish finish. Some repairs had to be done with all those years but it is still a nice example of an American or a Canadian made table, and I hope you've got the chairs with it. Only a few furniture makers were very popular with this type of furniture in New York State (for all East middle class customers). But mostly of the furnitures were done by private shops in small towns because of the significant low pricing factor and they were good woodworkers to reproduce most type of furnitures.

No I don't have the chairs, I wish I did.

This is a diagram of the sliders under your table.

Do you have sliders like that in the center of your table? If not, what supports that leaf?
If you notice the close up of the leg you will see where the stain has chipped and the light color shows it's not walnut. But I will say it may be ash.
I believe the top is veneered. Notice the picture of the edge and the top with no indication of separate planks or boards, then notice the picture of the underside with the obvious narrower boards making up the top.
Of course the legs are not sawed off, of else they wouldn't still have the holes for the casters.
There may have been only a few furniture makers of this type of furniture in New York State, but there were many many in Pennsylvania, Ohio, Illinois, Indiana Wisconsin etc.

Yes the sliders look like that, and it is not veneer on top. You can see the planks.

In 1876, casters were first patented by David A. Fisher, and were initially designed for furniture. Casters were not a must, but an addition to move the furniture. Furniture casters were viewed as a convenience. In most of the cases, casters had more to do with lighting than housekeeping or design. Casters were fit on the legs to allow the furniture to be moved around the room to capture the changing sunlight from the windows throughout the day.

Casters are of course older than the 19th century, but the use of them were very specific to the type of furniture. The earliest forms of furniture casters were made during the Queen Anne period in the early 1700s. Therefore, long before casters became common, early variations were being used with antique furniture. Further, many antique restoration shops eventually add casters to the mix to make the furniture a bit more durable if it has to be moved around often.

For this Victorian table, the period style and the 19th century American type, casters were not part of the basic design, and the legs, with the time, were getting worned up. Some antique shops were used to cut the bad tip of the legs. Still today some antique shops are keeping this process instead of to replacing the entire leg with new ones. Also to retrieve the correct high of the kitchen table they will add casters.

These pictures show the usual tip of the legs for you table, which are from the Victorian period. And no they were no casters. First picture shows the common tip, and the second picture too, but with the add of casters.

Wheels were add4ed to furniture to allow for easy cleaning.
David Fisher patented a type of castor used to move heavy pieces in factories, castors...wheels on furniture were used many many years before that.
The "Victorian era" stretched from 1837 to 1901....encompassing the early years if the industrial revolution.
The OP's table is not "Victorian">

Legs were getting "worned up"...what does that mean?
