I am sorting and typing about 30 plane frogs to sell and in the box found one that looks like a definite Stanley frog, 2-1/4" wide instead of the standard 2-3/8". On the back at the bottom it is stamped 5 1/2. I know there is one type of 5-1/2 Bedrock that has a 2-1/4" frog instead of the 2-3/8", is this also true of the Bailey types or what is going on here? The frog is painted green, I assume by a John Deere fan. Walter does not say anything about the different width frog that I can find.
