Can you ID this Shotgun?

[Sir Toast]

I got this side by side shotty many years ago. Its been in the family for more than 100 years. It is a 10 gauge, but I cannot see who manufactured it. I think the most distinctive thing is the lever that opens the gun. Rather than a fan tail looking thing, it is a looped thing that comes UP rather than moving to the side to open the chamber. Any help is appreciated.

Date of manufacture appears to be April 1892. There is another marking about 1891. (Sorry about the bad pictures. The IRS was having its way with me while I was trying to photograph the shotty.)

Thanks

Yes, it's called a "wall hanger".

I love those old guns.... look into the barrel and see the damascus twisted metal

It looks like a Remington-Whitmore. Based on the dates you gave, it is likely a Remington-Whitmore, Model 1878
Here is a Model 1874 (looks very similar):
