My grandfather had a large (50+) firearm collection. He passed away about 25 years ago and the relatives sold off most of it at that time. I just recently found out there were a few left and have been able to acquire them. I had no idea what was there but found some surprises when I got them. The one relevant to this forum is a Remington breach loading rifle. It is labeled as a .45-70 on a hand written tag affixed to it and in a bit of research this seems to be correct. It looks to be in decent condition, not great but not bad either. I did not see any rust on it. On the bottom is imprinted "REMINGTONS ILION N.Y. U.S.A. MAY 30 NOV. 15th 1854 APRIL 17th 1866" (or maybe 1886). Any idea what something like this might be worth?
