As the Colonel intimated, I have a few Camillus 72's plus what I've come to call clones which are different brands with the same dimensions, blade compliment & frame profile. There are a bunch of clones, many of which were made by Camillus.
Camillus did not stamp the pattern number on the back tang of the 1047s so don't get all nervous when you don't find one. That and the Scout shield are the only difference between the 72 and the 1047. The closed length is 3-5/8" period. Since Camillus is the parent of the #72 pattern, I go by Camillus specifications and they never made any 72s or 1047s in any other size. The blade compliment changed in early 1947 and again just before "end of business" and handle materials changed early on before Delrin® became the standard in the '60s. Of course they dropped the pile side sabre grind and later the mark side sabre grind around 1992, other than that the pattern has been fairly stable.
I hope this has been of some help.
