Keep looking, they are out there...
Cast brass....circa 1880 and after....
When looking the important thing to remember is the distance on center of the screws.
You might be better off looking for a whole set rather than just 2....but I would be happy with a mis matched set as long as all were "of the period".

Check out Vandykes restoration supply they have a web site at www.vandykes.com . They have many different styles, maybe not exactly like yours, but very close. Even if you have to buy a complete new set, they usually have some of the best prices out there. Also make sure you measure how far each pair of holes are apart on the drawers as Linda has said.

Try Horton's Brass (CT) on the web. High quality, lots of styles, American made. Measure your bore size before you order (distance between the posts). Also, Mitchell Brass (DE) and Ball&Ball Hardware (PA)

If you have had it refinished and restored chances are you decreased any vaule it might have had. For future reference it's better to find out first what you have and it's value as is before you decide on restoring or refinishing it.

Liz Hardware in Los Angeles had a store full of period, antique and just plain old hardware-- Knobs, handles, latches, and even old doorknobs and Chandeliers. They also have reproductions and new stuff. It was a walk down memory lane. You can buy on the web as I heard about them from a daughter in law who lives in Northern California and bought her knobs and cabinet handles on the internet from them. I tried to do a link but its LA Hardware Los angeles, or Liz Hardware.

Thanks for the help everybody, I'll try and see if I can find anything from the sources you listed. This is actually for my grandparents who chose to restore the item in question. They aren't interested in it's value, mostly it's current look and usage. :-)

Some of your bigger antique shops.Like Renningers,black Angus in Lancaster.There is a shop with all that stuff in one of them.The shops are about 3 miles apart.

Try House of Antique Hardware's website. The link is below.
I did not see your exact one but they have some similar. Their prices are very reasonable so you could always replace all the pulls instead.

This one is from The House of Antique Hardware that looks sort of similar.

www.castmetalparts.com will make any drawer pull you need cheap. If you have one they can make another.

One guy said it was a "Bombay Style"

He meant "bombé" (rounded front), not the Indian city.
