The S/N sure looks bad. Now, if Unalatova were to issue such orders, it would be reasonable that they either keep on going with the previous numbering, or they simply start anew. In any case, and Order of the October Revolution in the 60000 range simply does not make any sense.
I would love to see some better scans, but I think it could be an original order with polished back, messed up rivets and fake serial number. I am not sure, but the mint mark looks OK.

Her are better scans of this OOR... Hope it will help!
