Jeff's outfitters sells some nice stuff and his English style all leather cases make me wish I had a premium trap gun to put in one.
I have the exact same case as yours, only I put a Winchester (Miroku) model 95 takedown in 30-06 in it. Because of the box magazine on the 95, I had to swap out the lower left block to make it fit, but it came out real nice.
Here it is:
Also, you might want to check out a Hobby Lobby craft store if you have one, They had some inexpensive felt cloth craft rectangle's (about 9 x 12 in.) that perfectly matched the color and texture of the case lining, so even though he sent a small extra swatch, I needed more for both a barrel support and the filler foam block on the left end.
Beautiful 1894 by the way.
Cheers
