Hi Larry, I have all the HACO SA's I ever bought and I continue to try to buy every one I can. I have not counted them in a while but I think there are 15 or so in my SA collection. I have never seen another maker hand number them inside as HACO did, invariably, inside each one. The same number is on the grip as the tang, written in black ink. Sometimes on the top of the grip and sometimes on the lower part. Same for the crossguards, sometimes on the inside of the upper crossguard but mostly on the inside of the lower crossguard. I really like the individuality of that marking.
