Possible Unit Sticker in Holster?

[sporadicgenius]

I bought a holster today and since it had a sticker in it which appears to be a unit marking, I thought someone in this forum might have knowledge of this unit. (I don't think it's a name and address...) I can make out the first of the first word "Feld"...Field and then a further designation on the second line and then part of the town where the unit was from on the third line. The writing is in modern script but it has some characteristics of the old handschriften....can anyone help or direct me where to look?

Thanks,
Larry
