EIE Remington 1858 Brass Frame in 36?

[Patrick Henry Brown]

Picked up an 1858 Brass Frame Remington in 36 caliber from Prairie Dawg. Bottom of grip frame is marked "EIE Italy". Date code puts date of manufacture in 1972. Lots of endplay. Will need a bushing fore and aft on cylinder and either a new bolt or peen the bolt window as the lockup is rather loose. May not be worth the effort, but I always love to tinker on these guns. Anyway, does anyone have any info on EIE, their quality, parts availability or interchange, etc.?  And once again, it is not "FIE". It is definitely marked "EIE"
