Not fully assembled but trying to show what the skew looks like in this pic-

I bought this on ebay to try and clean up/sharpen and give to my brother as a xmas gift. I believe it is a type 19, first time venturing into the vintage hand-plane world (or any hand plane). It looks to be in pretty good shape but the frog sits on the base at a slight skew. I can correct it with the lateral adjuster if I crank it all the way to one side (not ideal). I think its related to this piece in the picture that the arrow is pointing to. I took everything apart to clean it up and when reassembling I forgot to add the collared screw that this plate sits in, leaving it free. I was able to square up the frog visually and it looked much better. Upon realizing i missed that screw I reassembled with the screw and this plate seated down onto it, again causing the frog to twist at the same skew.

Can this be fixed somehow?
