Currently there are a few guys from Austria that sell these unit marked SA's on egun and militaria321.
Looking at the rate in which these unit marked Sa's popup its easy to tell they are stamped recently, also often seen pressure/stamp bumps on the upper fitting etc...so they are forged quite a lot these days, ruin decent SA's for a few bucks by adding unit stamps
It makes me sick.
Btw yours is looking fine, all these fakes ive seen recently have double markings: upperfitting & Lower guard.
