Jackel - thanks for your post. Finally something from S. America! I am glad to hear there are some Oberndorf Mausers around as I was pretty sure there had to be. Can you recommend any dealers? The only one I have been able to find is:

They have a few interesting pieces, but no treasure trove of Mausers unfortunately. They do however have a well used Type S in 7.65 x 54 (see page 4 of the long guns section).

I think I might have better luck if I could speak Spanish!

Cheers
