Mitchells are typically refinished, force-matched parts guns that are made to look good and original, but are far from it.
Don't go there, unless you just want something that's nice to look at.
And that one... That one does not seem nice to look at.
The M48 is a Czech-made rifle produced after the end of WW2. They are basically a Mauser design, but they are slightly different from the 98s, the K98s, and the 24s (and 24/47s) in that the bolt is slightly shorter, so there is no parts interchange between the M48 series and the other, military Mausers.
The M48 is Yugoslavian. The Yugoslavian 24/47 is a Czech Mauser rebuilt in Yugoslavia. The M48 is a very nice Mauser variant. Although it is called an M48, they were actually manufactured in the early 1950s for export. I agree with going with an original M48 over the Mitchell's. The M48 also has a teak stock.
Further correction is required here.
24/47s were both rebuilds of FN 1924 (FN24) pattern rifles, as well as newly-manufactured.
M48s were both refurbs and newly manufactured.
FN24 pattern rifles were built by over a dozen different countries, with a huge number of them ending up in Yugoslavia at the end of their life, or after the war. The Serbs did not shy away from used rifles that cost pennies on the dollar, versus building from scratch. While a lot of the FN24s were Czech built, the majority were not. In fact, the majority of
Yugo 1924s were Belgian-made, by FN.
FN24 pattern production was always for military contracts. But 24/47 and M48 production did see some runs done specifically for export - with some fully intended to be sold on the civilian market.
The entire FN1924 family is short, not just the M48s. 1924, 24/47, M48, and a few specialty rifles in between. They use slightly shorter actions and shorter bolts (the "intermediate length" Mauser).
Unless the action had one or more rare modifications done, 1924, 24/47, and M48 bolts are interchangeable - often even for rifles produced in different countries, 30 years apart.
The rifle pictured isn't any of the above, though.
It's a German 98. With over-stamped Waffenamts.
