The German MK 412 was a late-WW2 aircraft cannon, a rival to the MK 112 in the same 55 mm calibre.
I have never seen one of the 55 x 205RB rounds, or a picture of one - only a sketch of the case, with measurements attached, and the knowledge that it used the same M-Geschoss shell as the MK 112. With this info, Mick Wilkinson has done a great job of making a representation of the round for me, machined out of solid aluminium as usual. Enjoy!
