I’m thinking of picking up some molding planes in my area for about $10 each in similar conditions as pictured. Should I be wary of those with similar cracks?

Would hanging a Stanley number 50 combination plane by the rails in this vertical manner or even in the horizontal position damage it over time?

Pictures are from mountain top joiners shop video of his tool cabinet tour.

Edit: thanks for the help everyone

I want to make this later type No. 5 into a fore plane but the rear threading in the body for the tote screw is dead. Any recommendations on fixing this? Epoxy? Rethreading or tapping a screw?

I recently got this no. 50 in good shape but I can’t get this spur out. I tried giving it a good soak in 3 in 1 oil and Houdini spray but it won’t budge.

Any other penetrating sprays or recommendations? I’m considering trying the heating method but unsure whether I’ll damage the body.
