Verwundetenabzeichen in silber (MM L54) + LDO etui / Hollow silver woundbadge (maker L54 in LDO case).
This is a very hard to find hollow silver woundbadge, maker marked L54 on the back (without “/”), which indicates production by maker Schauerte & Höhfeld.
In original burgundy LDO case, this case also maker marked L/54 on the back.
One of the hardest to find original maker marked woundbadge sets in good condition. I have not seen a matching L54 set in many years.
