Am working on a ID Guide for old car/truck jacks.   Need catalogs for "Ausco" and "Spun Steel" which seem to be the hardest to find.   Any other makes let me know what you have, digital copies are fine, more than willing to trade or pay for your time.

If you have any old jacks I can help you ID them, in exchange for permission to use photo rights.
