You are purchasing an excellent European reproduction of the data plate, caution tag, or nomenclature plate which mounted on the strip between the fuel and oil tank on 1942 and 1943 contract models for the United States Army for the big twin 74" UA flathead model.  These are simply the best ones on the market today and have been used on high point restorations for years.  This is a black enamel rubbed relief over brass.  It's a beautiful piece.  We also offer these nomenclature or data tags for all other H-D models used during WW-II.  Even if you don't own any of them, they are a neat trophy case item for your collection.

As far as "correctness" it seems H-D ceased using brass for generator, air cleaner, and other military nomenclature tags starting in 1944, so we are assuming a brass UA tag would be correct for 1942 and 1943 models.  Consulting Bruce Palmer's "How To Restore Your Military Harley-Davidson" will shed good light on this issue.

We sell a lot of WWII era NOS and spot on reproduction parts for your Harley-Davidson WLA, WLC, ELA, ELC, XA, and UA models.  We have many OD green parts ready to mount as well as hard to find parkerized and cad plated plain head and CP-1035 bolts as well as screws, wire clips, wire harnesses, the correct oil and gas hoses for Canadian military models, etc. If you do not see them here or cimarroncycleworks, just email and ask.
