Imperial Germany Medical Shoulder Board

[Linasl]

Hello everyone.  I am a collector and a seller.  I just received this pair of Imperial Germany Medical Shoulder Boards (see photos).  One of them is missing a 'pip'.

Can you tell me anything about them, like exact service, rank, time period, rarity, and anything else of interest?

Thank you.  Linas
