Reggio Registers

Ditto on cleaning and repainting...unless they're broken, then replacement is necessary. Reggio Registers is a big name, big price outfit, and they don't really look the part to me.
Not only antique stores, but salvage shops, and possibly old heating supply vendors--I got ductwork and the deep boxes needed to run a new line to my parlor at a local shop when the big stores like Lowes were clueless.
A local antique mall I go to had piles of grates, and I think the most expensive was about $25.00.

also check out flea markets, i see them there alot (but make sure you have your measurements and take a tape measure)

concure with others about clean and reuse what you have ...

If you have a salvage shop, check and see if they have them...but here's what we ended up doing for our old house. We had a strip-n-dip place strip the paint and finish from them, and then had a powdercoating place coat them. I didn't do the best job picking out the color so I'm not in love with that part (tried for "aged brass" but ended up with brown...d'oh!), but they work perfectly now and look clean and crisp, and it was only $300 to do an entire house worth of grates---much cheaper than buying replacements!

Thanks for all the suggestions! Stripping and repainting will work for some of them, but we have some that are pretty damaged :/ Now that I know it's possible, we'll see what we can do!

Since you're in Richmond, take a trip across the 14th St bridge to Caravati's. If anybody has old ones, it will be them.

"tried for "aged brass" but ended up with brown...d'oh!"

That is the color of aged brass, at least if it does not turn green from verdigris (copper chloride, copper carbonate, or copper acetate).

What the aging solutions do not tell you is to wipe away the chemical quickly on areas you want to stay lighter in color.

Like a door know will be brown in the middle of the knob and places seldom touched, but lighter (almost no color if used frequently) from hand contact on the diameter of the knob.

Oh, for sure---we were trying to get somewhat close to the brass doorknobs, which is why we chose that color. But since our registers aren't brass at all (some matte silver-colored metal---zinc, maybe, or steel?---they date to 1930 when heat was first put in), the color was just from the paint that was powdercoated on---so nothing to wipe off or not. It was a metallic tone that the place insisted would looked like brass, but in retrospect we should have just gone with black. Ah, well. At the time I had pipe dreams of eventually stripping the baseboards and thought black would look wrong with the oak, but now I know that a) it wouldn't have, and b) I am not going to strip the woodwork in this lifetime. Ah, well.

I think black would have looked Lucent with oak. I'm slowly renovating the 100+ year old farmhouse my hubby's grandfather built up fete in Northeast Oregon. I was looking for floor registers of that era and found myself here. It's been very interesting. Thank you everyone.

Refinish the best of them and use them in the highly visible places.

Replace the unfixable ones with modern stuff or repros.
