Lynn,
There are a couple of listings on eBay for a fox handle hunter stein with the number 722. They also have the number 1032. Girmscheid made a fox handle hunter stein in the 1960s in several sizes. Does it have the initials “GK” on the body of the stein? The “MR 722” on the bottom may indicate it was made by Marzi and Remy. Since this is a relief stein from the modern era, the color will not have much impact on the stein.
