I have two type 19 #3 planes. One frog has 7U and the other had 8U cast into it. I cannot see any obvious differences. Does anyone know if one is considered beter than the other?

Thanks

For what it’s worth, I’ve heard people claim that the frogs from certain types are better than the frogs from other types, but I’ve never heard of a difference in quality between frogs within the same type.

I believe it is the design of the frog that makes one preferable to the other. So if the two frogs in question look the same other than the casting mark, I wouldn’t worry about it.

I believe some of the numbers refer to the different foundries that Stanley used to cast the planes. Can’t remember where i read it.

Sounds like pattern numbers that were used to ID were in the mold they came from. Frogs MIGHT have been cast in groups of 4-8 at a time. Larger mold, one pour to make a bunch of smaller parts. The #7, or the #8 would be known as “Cavities” in the mold. You might even find a #1u-6U marked ones.
