Two cool equipment plates for a German vehicle. The larger says something about draining before removing the nut and was apparantly glued in place as there are no corner holes and glue residue on the reverse. the second translates to Transmission with maker code and serial numbers. I can not find the code fdp in any of my reference books and online searches tend to bring up a million returns for "free democratic party". This one was nailed into place. Two of the dome heads remain, one with a post still in place. Cool items, possibly even from a tank.
