@ GIJive and kammo-man,
Thanks for answering the question I had for the post. I was noticing some prior posts on the forum that mentioned that the backs of the snap buttons on the pants had maker marks like "Scoville" or other companies. My set of 44's has them on the back, however this set of P42's in the post does not. I'll post pics below. Just would like to know if some pairs don't have makers marks for future reference, I'm sure that other future collectors who read this would also find it helpful as this is not mentioned in any of the reference books I own, (dungarees and frogskin or gruntgear).
I also know I may be overthinking this or nitpicking to the nth degree, but I did notice that the pac man patterns are different on the jacket and the trousers, if it was made from the same fabric rolls I wonder why they would look different. Ill post some examples below. I thought all the pac men on these looked the same, I realized they don't once I also compared my set of 44's to the 42's. Were both variants were made from the same fabric pattern? I also realize that quality control was probably not the greatest then lol.
