My set is identical to this
Universal Model 39 set that just sold on Ebay for close to $400.00 with eleven bids. Looks like someone really wanted the levers and the calipers went for over a hundred in another auction. Anyway, just interested. Perhaps I will give Ebay a try again, and see what happens.
My levers have the same numbers stamped into them(this is the Ebay pic)...
