Excellent write up:
I have been quietly collecting these for years but now the secret is out as to just how undervalued they have been. I continue to look at all examples that come my way and lucked into an early WaA613 at a recent gun show where the seller clearly didn't know what he had. If memory serves me correctly there were only 10,000 Model 1922s with the WaA613 stamping and around 140,000 stamped WaA140.
