A fairly cheap proving ring can be made from the outer race of a large ball bearing. I picked them up from the scrap bin of a Construction machinery dealer dealing in large bull dozers. They came from bearings that had failed. However, the outer races looked fine and calibrated well. A little bit of attaching device machining needed and a dial ring of good precision is all that you need. Reading to 1/10,000 for the gage.

You are unlikely to find that any proving ring is of such a size that direct reading of the dial can be called the units of weight, such as a pound or Newton.
