By the prices seen at this site, old school desks used in country schools range from $30 to $100 per set. One set has the desk top with a seat for the next desk in front of it. The link below shows a desk with a fold-up top. These are more rare than the fixed top variety. One of the views shows a book storage bin. The book storage on fixed top desks was under the desk top. I spent my first 8 years of schooling sitting in a fixed top desk in a one room country school. Typical wood of the desk was oak. A row of desks was created by fastening the desks to two 1" thick strips of wood. A typical row contained 3 to 5 desks. These rows of desks could be moved to facilitate house keeping and rearranging.

Since it looks hand blown and of glass that has impurities in it...that green color. It could have been made last week ( but i's looks very dirty for that length of time!) or 3000 years ago. What's that gold color I see? is that in side the glass or outside? Is it dirt or remains of paint? The style of the handle reminds me of a Greek amphora....but with a foot.

Your last picture shows what is apparently a date: 2.1941. This would be February 1941. This could be the date it was assembled, or it could be a repairman's date. From this, I'd say that it was as old as 1941 and could be earlier. The pendulum weight is stamped with the number: 906. This could be a part number or pendulum style. That item that someone called a roller is not a roller. It is a drum that contains a power spring. The Roman numerals on the clock face all point to the center of the face, thus numerals 4 through 8 are upside down. This was the style of early clocks and at some point, clock makers turned over numerals 4 through 8 so that the '6' was right-side-up. I have forgotten at what date this occurred; I believe it was in the 1800s. However, this was not a hard rule that everyone adhered to; It was more of a style change. Since your clock has a rather compact spring driven mechanism, I do not think is was built in the 1800s. Yet today, some clocks are made with all numerals pointing toward the center simulating an old clock. Many early clocks ca 1830 were weight driven. A number of spring contraptions were tried before the introduction of the power spring, but it was difficult to build a clock that could run for 8 days with these primitive devices, The introduction of the power spring made it possible to shrink the clockworks and have a run time of 8 days. Early power springs had a habit of breaking until better technology and stress analysis improved this spring. The construction of your clockworks does have design elements that were in use during the 1830s. Its frame is two flat plates. The base plate has 4 pins riveted to it and the top plate slides onto these pins. The pins have a reduced diameter on their upper ends making shoulder pins. The top plate rests on these shoulders. That top plate is fastened by tapered pins inserted through holes in the frame pins. I do not know how long this type of construction was used. I do know that it was common in the 1830s for weight driven shelf clocks. The other element is the beveled holes for the shafts of the final gears in the gear train. This little recess is a oil reservoir for lubricating the shafts. Oil will stay in this bevel by surface tension if it is not flooded. Unfortunately, these details do not pin down a date for this clock. Look over the interior of this clock case. Was there a label? A Maker's label was often put in quality clocks and these labels can be very helpful in determining a date. The label may have the date of invention or patent. This label may be on the inside of the case back. If it is there, use care to preserve it. There can be up to 3 identities in a clock: The manufacturer of the clockworks, the case maker, and the business establishment who distributed and marketed the clock. Often, a clock maker buys the clockworks and installs it in his case. In another example, a jeweler may specify the clockworks, its pendulum and contract with a clock-maker to make the case and assemble the clock. The Jeweler's name may appear on the clock label. Hopefully, he credits the others involved.

those screws would go all the way from the top, down through the "apron," and then into the leg to sandwich it all together so the leg will not wobble. The way the leg is made, it's like a tendon at the top that is wedged into an opening in the apron. there may not be any dowels in it, but the markings at this mitered joint make me think it was marked, so that holes could be drilled for a dowel, and then if drilled on those marks it would go back together and line up the pieces.
