Posted 19 November 2003 02:43 George, These piped cuffs can be found, also on different ranks.
I attach two pictures. First shows frontal and back shot of the pre1936 Feuerl�schpolizei tunic. (this one is different from yours in that it has slip-on boards, no piped cuffs and other insignia)
Second picture is a detail from a group of feuerwehr men. The piping along the cuff can (only just) be seen. No buttons are present on the cuff
BTW the Kn�tel drawing posted by Patrick also shows the piped Cuffs without buttons.
