Thousands of Upholstery Staples in Various Sizes, all with 3/8" Crown

Description

I have five open boxes of staples that were used in an upholstery business. Two of them are marked Empire 7-1/2, made in France. Two others are marked 9/16, also made in France. One box of smaller ones is marked 7-1/4, made in W. Germany. I don't know what brand or models of staple guns these may fit. I think they are all 22 gauge and that they all have a 3/8" crown width. They all have chisel points. I do not know what they are made of - they have a copper color to them - may be stainless steel, but I just don't know. There are probably a total of over 30,000 staples all together.
My guess on these is as follows:
The 2 boxes marked 7 1/2 and "Made in France" have a 7/16" leg - there are probably 15,000 staples
The 2 boxes with open tops are marked "Made in France", and have a 9/16" leg with close to 8,000 staples
The one nearly full box is marked "Made in W. Germany", I think have a 1/4" leg and has about 9,000 staples
Let me know if you have any questions and I'll do my best to answer them.
