Mitchell’s Mausers are Garbage. Don’t waste your money on a Hump Job.
They're "humped" and expensive for what you're getting.
On the other hand, they look very nice, usually have excellent bores and shoot very well.
They are not collectible status IMHO.
Still, if you want a pretty, representative shooter, they're just fine.
Mitchell's took on all sorts of refurbishment projects. I've heard all sorts of stories about where they got the arms from, which mostly say they came out of East European storage, mostly as parts or partial rifles, that didn't make it to refurbishment. It would not be presumptuous to make such an assessment.
As for all non matching??? Not so. I bought up an estate sale about a decade back and the fellow had nothing but Mitchell's products in his den, which was really a very large walk in safe.
There were four laminated stock late war K98s with different manufacturing codes but receivers dated from 1941-1945(swp). All were matching numbers and all were polished to a high luster. They also had all issue accessories and matching bayos.
There were also four Walnut stocked K98s with dates from 1936-1940. All were mismatched numbers and all were polished to a high luster.
He had C96, P08, P38 pistols and a couple of dewat smgs, an MP38 and an MP40, along with about a dozen helmets and a few medals/flags, with dozens of books.
It made for a very nice collection. None of the helmets, flags, medals were authentic but they were in pristine condition and for most people looking at them, were as real as they wanted them to be.
His wife had all the bills and import papers for everything. She was under the impression the stuff was worth way more than he had paid for it. Took her a couple of months to get over the shock of his death as well as what the real value of the collection was.
