I received this knife and others in 1985 after my grandmothers husband passed away. I have been going through them and thinking about selling a few. It seems as though there is a lot of interest in the R1263 knife but the only info that I can seem to find is on the 1986 re-make. This is a vintage knife and came with a bunch of old Union and Case knives. Any ideas on where to look to get more info and an approximate value? Thanks
