Today I found a #29 English Jack. It is kinda raggedy, blades are scratched, the bone is good though and it should cleanup pretty well. This one has a '52-'55 tang stamp. It was laying on a table all by itself, surrounded by stuff at a flea market. The pen really snaps but the spear is a bit lazy, kinda like me. Just noticed the blade looks short in the picture, it is a bad picture angle.
