I recently purchased a Schrade-Walden Uncle Henry 227UH. The chart at http://www.allaboutpocketknives.com/sch ... _henry.php
indicates it was manufactured from 1973 to 1986. The knife appears to be made from the Schrade-Walden 225H pattern.
The tang step on the knife is:
The stamping is unusual because the "Stainless" portion has taken the place of N.Y. USA.
The tang stamp on the 225H is:
With the "Stainless" stamp and the Schrade-Walden lable it is obvious this knife would have to be an early edition of the 227UH, perhaps being made when tang stamps were in flux.
I had a 227UH (which I should have bought more than one of and kept in NIB as an investment) in '80 or '81. It had the standard Schrade+ tang stamp. Every other 227UH I have seen, with the exception of those made by Taylor, use the Schrade+ stamp.
The stamp does not match any of the stamps below:
The closest match is the 1973 Schrade-Walden tang stamp, but it omits the N.Y. USA.
