My IMPER1AL is a two blade, jack knife measuring 5.25" closed, the shield is marked "DE" (Sharpleigh Hardware Co.) three pin with brass a liner. The tang mark was used from 1956 -1988.
The 255H was produced 1957 - 1975 but the tang is not marked "225H" so is it a different model or a 225H?
Anyone have one of these or know more than me about this knife?
Thanks
