From the picture it looks pretty clean , can't see rust on other side. If rust is minimal I would say $450-$550 depending on part of the country. The 35 remington chamber does demand more money. I paid $550 for a clean 35 SC model made in 1955 a few years ago and felt price was fair. I don't think it was ever carried hunting and shot very little if any. Probably could have been put away and resold as a collector quality but I don't collect , I use and hunt with everything I own.
