The stamp is much more likely to be an inspectors, units or manufacturer's stamp.

Aha, I had thought of that too (about the inspector's, unit's or manufacturer's stamp), but I went for the "personal" approach... which is in most cases not the "rational" solution.
In other words: you're right. Thanks for your insights!
