maybe 4-5 week ago a friend from finland send me pics of a kurz mauser in 250 -3000. maybe you know him - cristian alias bokmal? the mauser was for sale but imho, the owner very old had it still on licence. I forwarded the pics to kuduae because he is the specialist for this and he confirmed it was a very early post ww 1 mauser made in 1919/20. finnish modification was a straigt bolt handle maybe for better handling with thick glowes in winter time. I have trouble with my email account so can't show the pics of this rifle here.
if you don't have a licence just now it would be worth to park the rifle on a dealers licence.
