Kip, you may be in luck. I believe I have four of the six-lug artillery wheels you are talking about and don't plan on using them. I am looking for two more of the 14-16 spoke 3/4 ton wheels myself. Anyways all but one seem to be in decent shape asides from little surface rust. in fact...one appeared to have been spray painted flat black which is peeling off revealing what looks to be original army green underneath. I'll take some close up pics of them for you and see what you think.
