I checked the one with the pin like your's, Dale. It's 94393, a straight grip GH, but looks like a replacement stock. The pin repair was like your's and this CH that Patrick Lien posted for sale last month. Patrick's has brass where mine and your's are steel. It would be interesting to see one that letters as original or a factory repair. The CH pin has more engraving.
