what is this worth today? a 1918 Mauser T-Gewehr 13mm anti tank rifle. The first anti-tank rifle ever made and is fully functional with 2 live rounds and 1 display dud. Complete with Bi-Pod. I've seen a few in museums and never seen one for sale. I know that around 18000 were made for WW1 and all Europeen ones were decommissioned and rendered non firering. This one is fully functional and packs a serious wallop! any idea on the value would be appreciated.
