Stanley planes circa 1905, frog adjusting screw?

[Mike Holbrook]

I was looking at some Stanley planes some manufactured from 1900- 1910. I read that prior to those dates there was no screw to adjust frog position on the plane body. I guess the blades on these planes would all have to have the mouth gap that was manufactured into the frog/body? I suspect that a slightly thicker or thinner plane blade would be the only variable? These planes might not even work with the new LV plane blades which I think are a little thicker?

you can still loosen the frog hold-down screws and move the frog to close up the mouth on the earlier models.

all that was missing was the "screw and plate" frog adjuster

Ahhh, that is exactly what I was wondering Joe, thanks. I could not tell from pictures.
