Remington Model 3? Single Shot

[Dee]

I have an old Remington Single Shot break down, with a cocking LEVER on the left side of the breach. I believe it is a Model 3, and it was made around 1903 I THINK. The shotgun locks up tighter than a bank vault, and should be safe for low brass ammo, and I have been thinking about making a squirrel gun out of it. It is in really good shape except the barrel lock lever, seems to have a spring missing. Have disassembled it and it doesn't seem to be there.
Anyone know if I am correct, and does anyone have a skematic of the shotgun?

i think i have the same gun with maybe the same prob, does yours lock if you pull the top lever back in place? does yours have the button on the tip of the forearm?i got this gun from my granpa years ago and havent really done much with it. its pretty rough but i have safely shot low brass dove loads thru it although im not sure id reccomend it without a good chekup at the smiths first.

No button, it has a lever on the left side that locks the barrel into the receiver. Neat set up. The gun is about 85% condition. Tighter than a bank vault. I have given it a good going over, it's safe to shoot, however my oldest son played gunsmith and took it apart to clean it, and broke the return spring. Looking at the action, I suspect it was a leaf spring. He didn't think to keep the spring, or I could have made one, with a look at the old one.
