Need fuse block replacment help

I know this is not the right forum, but, if you know a better place, I would appreciate it if you told me where. I have an Amalgamated Electric Company LTD. Model 303 fuse block that blew a contact. I need to find a suitable replacement. The company went under in 1979, I think. I don't know if a substitute was ever made for this, or if it was a standard unit. It is a pull-out, bolt-down, dual P-type (60A/240V) fuse holder, that sits on rails. I would just use an external breaker, but there is no room near the fuse box, and I need to keep it as inexpensive as possible. Any ideas?
I don't usually do house wiring, but if anyone knows anything, I would like some help.
