Hello,
need help with this unit marks. I have many this knives, but any with marks like that. Maybe Sapeur Regiment ? Producer s R. Thanks all for help

It could be 29 Schutzen regiment from Češke Budjovice (Budweis). 145 is perhaps an regiment inventory number. There were no Sappeur regiments, just battallions if I remember correctly.

I agree, Schuetzen Regiment 29
