Thank you Russ for the accurate info. It is helpful, because Iam really tired to explain to almost everybody of visitors about such tugs. Yes, it is NOT "escape tickets".Iam sure too! One more to public view: DO NOT trust to any speculators, ebay sellers, who offer an "stalingrad relics". It is scam usually. This stuff may be purshased from everywhere for resale purposes as stalingrad relics.
