It's worth whatever you can get for it. M. Spaziani; SPAZ'S GUN SHOP; Easton, PA.
Would have to at least know the model and condition would be a huge plus for determining value, also it's a .35 Remington not mm. Probably is a model 8 or 81. Well unless it's a .35 Whelen and that would be a more modern rifle like a 7400.
If nothing else the date code on the barrel. 35 and later would be a 141 vs the 41. See related links for reference to the Remington Society of America website for date code details
100-1000 USD or more depending on specifics
No 35 Remington fired only 35 rem. The 35 Remington is a good cartridge, it's a little more difficult to find but it is still being made.
