Traded for these two at my garage sale today. The little one is Planet Jr 5430 but the big one has me stumped. No marking. 1/2 inch thick malleable (my guess) casting. Seems like I may have seen it before but my recaller needs updating. Anyone give me a clue ?
obvious repaint.

Wow!  No idea at all.
But could it be made to hang over a garage rafter so that you could bang your forehead into it in the dark?  Looks like it would be just right for that....
