From only such that are listed, the format of pattern numbers have been changed in 1953, 1960. Also the material of the handles progressed from wood, to genuine bone stag, to bonite, and finally to staglon. Of course, the patterns of knives have changed the inventory of production knives on the market. And the tang stamp signature has been redesigned, most early knives had no pattern numbers.
Just common sense says this is the challenge involved in knife collecting. So I am hoping the builders ofWWW.Collectors-of-Schrades-R.us have any other pages to add to this "one of a kind" resource.
