I recently purchased this metal pennant that was dug at Stalingrad. A friend of mine goes there every summer and digs. He got this pennant from one of his friends who digs. I believe it is a battalion marker to denote the battalion HQ (maybe??). It is marked 733, which I believe stands for the 733 Heavy Artillery Battalion which was destroyed at Stalingrad. This battalion was attached to the 24th Panzer Div in Oct. of 1942.
It measures about 15 1/2 inches wide and is red on the top and bottom with black center portion. The front side is still readable and the back side is all surface rust.
Is there anyway that I can clean the rust from the pennant safely? Or maybe so I can "improve" the readability of the front side? Also, I would like to keep
it from rusting anymore than it already is.
