Simply because Travis people are uneducated in what they truly have. Most of the Russian steel 40's were in lots of East German mags and thus are sold as "East German RPK Mags" or "DDR 40 Rounders!" as was the case with mine.
whatacountry.com has East German steel 40s advertised.
Problem is when you do find a source and when you send people a pic of the Molot stamp on the spine they don't give a shit about screening out the goods just how many ya want and how you going to pay.
Thats how I got my Molot 40 round mag. It was supposed to be a East German mag. I got it with a bunch of EG 30 rounders. Was not until years later that I learned what that stamp ment on the upper rib. The only russian mag I have.
