The sirens were removed from the B-series onwards. They installed the sirens on the bombs instead for the same effect. Also if we talk about '44 scenario, the SD 50 were more and more replaced by SD 70 bombs which an be fitted at the same bomb-rack

Or you drop 4x AB-70 (AB-70-5 = 50 SD-1 or AB 70-D-1 = 23 SD-2 each) out of the ETC-50 rack.

If you want to go against tanks, take the MK 101 or MK 103 and load the "3 cm H-PzGr.Patr. L'spur o. Zerl.". Weight 356g It has a 231g Wolfram-Karbid core. This bullet can go through 100mm steel (100kg/mm² solidity) by a distance of 100m and 95mm steel by 300m. By a solidity of 150kg/mm² it still penetrates 78mm (at 100m) and 74mm (at 300m). Vo = 960m/s with an energy of 16727 mkg at a distance of 0m, 15563 mkg at 100m, 13486 mkg at 300m and still 8270 mkg at 1000m. Mix some "3 cm Pz.Spr.Gr.Patr. L'spur o. Zerl." (can go through 32mm steel (150kg/mm²) at 300m and 27mm steel at 600m) in it and have fun.

From the L.Dv.4000.10 "Munitionsvorschrift für Fliegerbordwaffen" The "3 cm M.-Geschosspatrone 108 El. o. Zerl." has 100g HA 41, a high explosive dynamite. bullet weight 330g. The "3 cm M.-Geschosspatrone L'spur 108 El. o. Zerl." is identical to the MK101 and 103 bullet (series L) and has 72g of HAT 41 + Nitropenta. The tracer (L'spur) is up to 1200m active. Later models had selfdestructive fuses (m. Zerl.). There also exist the "3 cm M-BrGr. m. Zerl.", a mineshell with ~40g HAT 41 and 20~25g incendiary. Complete weight of the bullet 370g. And incendiary bullets "3 cm BrGr. o.Zerl.", in the construction equal to "3 cm M.-Geschosspatrone 108 El. o. Zerl" but filled with incendiary instead of explosive. bullet weight 330g Ammunition for the MK 103 are equal to the MK 101, but using an electrical fuse for the cartridge instead of a mechanical.

Small summary from the Fw 190 A-6 handbook Teil 8B page 13 "Bombennotzug" The bomb(s) is only armed after master arm on and selected fuze time (oV/mV) on the ZSK, since it's an electrical fuze. The bomb can be dropped unarmed (one or both switches of) through the emergency handle, because the cable goes directly to the ETC-501. The bomb can be dropped armed through emergency handle, if master arm is on and ZSK fuse is selected. An exception is the ER4-rack (4x SC-50), it will be dropped unarmed through the emergency handle equally your settings (electrical wires will be ripped of by emergency release). The military regulation for emergency drop was: on friendly territory drop unarmed, on enemy territory drop armed. I hope that helps.

First of all it should be written as "Aus"! Second: the electrical circuits are seperated by usage in german aircraft with a simple alphabetic code. The position within the circuit is given by a number. E = Elektrische Antriebe und Überwachung für Flug- und Triebwerk (electrical devices and control for airframe and engine) from "Bf 109 K-4 Handbook Teil 9B-1" Page 8 I hope this helps.

The other problem could be that you can't fly inverted for longer than that 30 seconds (as in the report given), because the electric pump is not a flexible submerged pump but a static submerged pump. The Bf 109 G-K has a the electric fuel pump 8-4544-K from DBU. An internet search delivered me a 8-4544-H. But if you look into the manuals of the 109, for pictures, even the E-series had a static pump. Fuel tank attachments of the Bf 109 E

I./ZG15 Falke quote is correct. Original text at page 7 from "Werkschrift 2109 K-4; Bf 109 K-4 Flugzeug Handbuch Teil 7": Die Behälterpumpe dient der zusätlichen Förderung des Kraftstoffes bei absinkendem Kraftsoffdruck und wird vor Anlassen des Triebwerkes eingeschaltet und erst bei Abstellen des Triebwerkes abgeschaltet. Schalter hierfür in Selbstschalterträger (Führerraum rechts). Also interresting last two sentences from page 8, same manual: Vor Beginn von Kampfhandlungen ist der Kraftstoff des Kraftstoff-Zusatzbehälters im Rumpfende über den Schnellablass abzulassen. Handhebel hierzu im Führerraum rechts. translated: Before beginning the battle release the fuel of the auxilary fuel tank in the fuselage end throught the fast drain (valve). Handlever hereto in the cockpit right.

noticed some bugs and wrong control column. Major: grass in cockpit!! model error: control column (see attached pics from the manual) minor: wrong color of right radiator handle and emergency bomb drop handle

The only museum with a EZ 42 gunsight, which i could find for now, is the Smithonian National Air and Space museum See: http://airandspace.si.edu/collections/artifact.cfm?object=nasm_A19601563000 I tried to find the other mentioned manual through the german Bundesarchiv and ZMSBw, but no luck.
