This is a mint unissued cufftitle for the rank of Oberzugfuhrer this and the Chef der Bahnschutz are the only two cuuftitles for a single rank. although any bahnschhutz cufftitles are very hard to find this is the most common and the one you will see come up for sale here and there due to the fact that a small cache of these were found in koln in the mid 90s.
 priced about $400 less than other sites.
