I just picked up this small Navy "Amphibious Forces" uniform group. I paid entirely too much for it, but the seller was splitting up the uniform piece by piece and I didn't have the heart to see everything scattered to the wind. Included in the group are the jumper, pants, and neckerchief. All 3 pieces are named to the vet, Motor Machinist's Mate 1st Class (MOMM1c) G. L. Glover Jr. I found a George L. Glover Jr. in the 1930 and 1920 Census records native to Rhode Island (same area of the Ebay seller it was purchased from) that may have been the original owner, which sending off for records will hopefully clear up. The uniform set is in exceptional condition, with absolutely no mothing.
The construction of the rating patch is interesting. Usually, they are simply a sewn-on patch with the eagle, rate, and rank (1st class, 2nd class, etc.) all on the patch. However, on this jumper, each component is sewn on individually. The eagle is a separate patch, the Motor Machinist's Mate rate is a separate patch (of the type seen on jumpers where the sailor hasn't yet become a petty officer), and each chevron is an individual piece of cotton fabric sewn onto the sleeve. It's certainly different and appears completely original. Haven't seen another like it!
Anyway, check it out and feel free to comment!
