In perfect condition. The engine type stamped on the case is "77/911" and this crankcase actually belongs to a 74' RS now somewhere without its original engine. The case was checked by Ollie's Machine Shop, ligned-bored, flushed cleaned, media tumbled and ready for an engine build. More photos to come.

PS: The 74/RS and the 74/RSR both used the same engine crankcase and the 'type' number stamped on the case was different due to engine specifications (induction, camshafts, etc.).
