HELP! Hecules shocks??

I recently purchased a bunch of old inventory from a closed garage. I am now the "proud" owner of BOXES of shocks still in their original box and I have absolutely no idea what they fit. No reference at all. The shock boxes are white with black & red lettering. They say "Hercules Shock Co. Cleveland, OH" I cannot find any reference to this company. The part numbers are still on the boxes if anyone knows anything about these. I'm sure they are from the 50's or even older as everything else I got was :-(.
Any help would be appreciated. Please e-mail [email protected]
