Sorry if I am placing this in the wrong place - I did not see an Italian LMG page.
I just got this from the same gentleman I got my Type 11 from (see on Japanese section). This is a Costa Rican contract 7mm Mauser. It is a rewat. 2-digit serial number (as most Costa Rican contract guns are). This has a lot of matching parts but it is not all matching. I have not shot it as I just got it today, but it hand cycles nicely. I know these are known as "dogs" in the MG world, but I have always been intrigued by its design and look. I was not really actively looking for one but the guy who sold me the Type 11 happened to have this one and he made me a great package deal on the two, so I could not say no.
The seller was kind enough to throw in a *mostly* complete parts kit with it, which was not originally in the agreed upon price or package - so that was a pleasant surprise. The kit is just missing the barrel, magazine and mid receiver section. I also got 2 Costa Rican marked boxes each holding several stripper clips. Anyway, thanks for looking!
