Hello all,

I know that HB-50's have serials that start with the year 095XXX and so forth. However, mine starts 74XXXX. Also, on each of the slides there is a 74 stamped on it. Any ideas?

Cheers,
Kory

My HB-21 is the same way. However my serial number goes with the year 092XXX, but I have 44 on the slides. I've always wondered about the numbers stamped on the slides. Let us know what you hear from Mr. Hirsbrunner.
