In general.
Mitchell's Mausers takes milsurps and gives them a makeover, and an expensive one at that. If you want a pretty, expensive, otherwise shooter grade milsurp, they are your ticket.
K98 - World War II era German carbine, source unknown (likely Russian capture at present). Various manufacturers (Germany made their guns at any factory that could qualify). Some manufacturers are more rare, but Mitchells makes no distinction. Late war manufacturing standards and quality are poor compared to pre- and early war.
M24/47 - Yugoslavia under took a standardization and modernization program of their M1924 Mausers to this new configuration.
M48 - A follow on program of a series (M48, M48A, M48A(B), M48(BO)) Yugoslavian produced rifles with further standardization and simplified manufacture. Zastava in Serbia still makes similar rifles to this day.
