thank you for your words of encouragement, you know real inventor's work for the common good. I have another secret invention for an older problem that will come to dayligth this year.

in the beginning I dont know what to do with the patch box. does it fit, is it a good idea? will I need it in the future for another rifle?
The dreyse jaeger rifle was probably the first one without a patch box but you will find it on sporting guns up into the 1870s. The rare Dörsch&v.Baumgarten needle fire jaeger rifle for the tiny Principality of Schaumburg-Lippe in germany had a patch box.

Dörsch was working for Dreyse before he became a master in Suhl on his own in 1857, only Schaumburg-Lippe order 670-750 jaeger rifles of this model for the dreyse military cartridge in 1861.
600 of this jäger rifles were sold to japan in 1868 were a Feldwebel Carl Koeppen trained a unit near Osaka as a foreign advisor or お雇い外国人 with this needle rifles.

Dörsch&v.Baumgarten were also making hunting rifles with this action but in the own 12mm caliber.
