There is a possible explanation for the serial numbers above 3500.
In a perfect world there would be 3500 pistols numbered 1 to 3500. But, a number of pistols would likely fail the production tests and others could even have been rejected on arrival, the circled triangle acceptance mark must mean something afterall
, so in order to fullfill a 3500, contract the serial numbers may run higher than 3500, but there must be some gaps in between.
Off course I've not a shred of evidence to support this.
