Re: Collath Drilling and Arms

a mister Roth in germany has worked on a book about teschner-collath 10 years ago in germany but his computer crashed when he was close to end and he never make it again.
collath was the successor of teschner and use his action till world war 2.
the teschner gun startet around 1855-60 as a special kind of needle fire system. It had have the the needle in the cartridge base like you see on pic 2. this was the teschner priming and in produktion with other Tesco shotgun cartridges till the end.
pic 3 is from the 1914 catalog and it was lot of money in this time. i dont believe that the design changed after this.
pic 4 show the shotgun cartridges from the 1914 catalog. No 1 ,3 and 4 are the most common of the tesco cartridges. you see also cartridges with center fire tesco primer for using in the same guns.
german colour code for blackpowder shotgun cartridges was green and red for nitro, even the last RWS center fire black powder shotshell 30 years ago had have green shells.
the length for the tesco shells goes from 66 to 74 mm and the chamber must be conical to accept all length's.












the black is a 16/70 for comparison
