Collecting militaria, different but,,,,,,. A german k98 rifle can sell for thousands depending on make, year and condition. If any parts are not matching numbers (UNLESS) its armorers replacement parts it is considered altered or not original. If it's a missmash of parts put together but the Russians after being captured or otherwise stock sanded to make it purdy, drilled and tapped for a scope for a hunter the value goes down exponentially.
Not an equal comparison and I'll let you guys settle this and quote you years from.
