Not sure if this is the right one, centre drawing, black and red ?
Sorry guys I Don't speak German but are these pics any good ?
I cannot find any reference to 4.7 photoflash only 4.5 photoflash
These are the only photos i have of the end ,This is the part arrowed in the drawing..Its about 3 years since we found this but If i remember correctly the centre piece was some type of zinc alloy
Hi i aquired this one which is similar, last year the nose plug is marked No15 1C and is made of iron holder is threaded and made of brass .
It should be mentioned that this is the filling hole not the fuzed part of the 30 IB
See attached pictures Cheers
