I think that $750 is optimistic, but I could be wrong. It is obviously a cut-up 94, that's been dressed up, nothing exceptional but the take-down. It has zero collector value, and might or might not make a good shooter. In my (limited|) experience, cut-down rifles tend to not be great shooters. My (once again, limited) experience has been that it is pretty tough to get a lot of money out of a model 94.
As always, YMMV.
