12ga or 16ga?
Ejectors or Extractor?
The D Grade is a very desirable gun to collectors and vintage SxS shooters when in good condition. 16ga editions are somewhat rare.
All the 1894's are ser#'d starting at 100,000 and I believe never hit the 2oo,000 mark.
I'd sign up over on Doublegunshop .com

Then post what you have on the DoubleGun BBS Forum.
Pics and info, ect. You'll get plenty of comments. They can be a bit tough at times, but a few are truely passionate about these.
One long time member posts under the screen name of 'Resercher' (also posts on several other gun collecting sites with that name.
His name is Dave and he is just packed with info and is especially interested in the Remington SxS's,,Model 1894 in particular,
A 'D Grade' posting will catch his interest and no doubt get a reply or more about which way to go with it and some suggestions.
I have a project D Grade 1894 also. Bought off of a flea market table of bicycle parts, auto tools and archery stuff. It's seen a hard life and is missing a couple small parts but have those in hand now.
A 12ga Damascus with the ribs loose, bbls rusty on the outside, forend looks like it got too close to the wood stove and charred!.
But it's a D grade,,,,and a project for 'sometime' in the future.
I'm retired from the gun restoration/engraving biz now. 50yrs, time for some projects of my own.
We restore them 'cause they are there and because we like to.
Others go fishing or play golf...
