It is represented as a vendolator Model 81 as indicated on the ID tag and embossed with royal crown. Nothing more or nothing less.
He didn't lie here but I also noticed he didn't post the above questions on his auction for the public to see.
He paid $800.00 for a generic door, so he must have wanted it pretty bad.
I'm quite certain he had it stamped but a collector needing an RC machine to complete the set may have bought it anyway even if he had been honest.
I would have trouble sleeping at night if I were the seller.
