I would say the guess on this kit for the year is pretty correct. The pattern on the WMP on this kit is the same style that WFL used on Zephyr lug sets from the 30's and 40's. Classic lugs and speed king upgrade was done in 1946-47 and some of the earliest WFL classic lug sets I have seen used small classic lugs on the 9x13's. Those claws also look 40's WFL claws that were used during the zephyr lug period. I know they never wasted anything so at some point everything was used up. The WMP pattern changed in the late 40's to the more straight lined look and the new style WFL claw then had WFL written right on them. WFL also did not come out with legs mounted in the bass drum until the early 50's. Your set looks like a great example of a period correct late 40's set. I had a 24,13,16 6.5x14 snare in wmp myself and I sold it a number of years ago. Actually I think Tommy P has it now and it was a beauty. Mine had silver badges, wfl stamped claws and the 50's style WMP. Judging by my snare drum I actually think my set may have been a 48-49. The legs were hoop mounted as well. Thanks for posting those pics!
Ok I have included close ups of the badges and their is a difference, Bass Drum, Tom (floor tom is exactly same) and snare
These do appear to be different years.
