Aluminium-based, WH (Heeres) ie. 'Pioniere- o. Bau-Truppen'-related ID-disc bearing the clearly stamped unit-designation: '3./Pi.Btl. 752' and that comes as issued and/or worn

This is an attractive example of a silverish-coloured- and/or typical aluminium-based, WH (Heeres) ie. 'Pioniere- o. Bau-Truppen'-related ID-disc (ie. 'Erkennungsmarke') that is bearing the clearly stamped unit-designation that simply reads: '3./Pi.Btl. 752' (and as such being a disc that was I deem intended for a soldier or NCO who served within the: third company of the 'Pionier-Bataillon' (ie. construction- ie. enigineers-battalion), numbered: '752') and that comes in an overall nice- (albeit clearly used ie. worn-), condition. The attractive disc comes in overall nice condition (and is executed in an attractive letter-type!) and shows the clear evidence of having been used ie. worn (it shows somewhat torn-out holes as can be seen on the pictures). The disc shows a clearly-present bearers'-blood-group-type (Type: 0) something that is more often but not always observed. The disc was never cleaned nor polished (it is still a bit stained and/or dirty). The disc originates from a private-household in Germany where it was recently uncovered. Simply an attractive and honest WH (Heeres) ie. 'Pioniere- o. Bau-Truppen'-related ID-disc that is with certainty accordingly priced!
