Looks like Lohr's lures in that pic. His tail shape was unique and he used plastic lips. The WEC baits use lexan lips as do most of the copies I've seen.
I build my version from 1/2 stock, 1/8oz of ballast, and a straight lip that is 1 3/4 inch long. I think the length of the body is 2.5 inches long. I have a Blazer
Tapp in box somewhere and my pattern was built similar.
