@johnb, @holzhamer, @starfar, @fiveten, @gblair and @faraomike, the two E-3a’s are about to move to their own topics, just one final digging in on them both, as the matter in hand seem to concern both Swiss and Romanian planes.
20 mm in the wings
In this last post on my two Tamiya 109 E-3’s the matter of the wing-mounted guns are discussed.
Back in 1914, a patent was taken out on a machinegun by german Reinholt Becker. As Germany was forbidden to make weapons after the end of WW I, the work was taken to Switzerland. The weapon ended up being made by Oerlikon, and exported to a lot of nations.
The machineguns were also manufactured in Germany at the outbreak of WWII. The German version were operated by electro-pneumatic re-loading whereas the Swiss version had to be charged on the ground by means of a lever.
This difference (a bit basically described I know) meant that where the german MG FF had a faired spring along the barrel, the swiss just had the barrel protruding. What to do?
-
1. WHAT! - japanese guns in German wings?
2. ABER
3. Master-Modell
Well – the Oerlikons were also exported (manufactured) in Japan, and the MG actually happened to be on the Zero! So, you just buy a set of Japanese 20mm guns and install these. Job done!
And now the two 109E-3a’s will get their own topics to enjoy. Please feel free to follow them when they eventually re-appear on their own!
