Milk Runs in the MED

I think you meant the E-1/E-3 and why they have been built simultaniously. I don't really know, maybe they just had not enough cannons or wings to mount them (E-1 wings had to be modified with bulges to fit the cannon).
Nobody seems to know what the issue is/was with the E-2.
I hope nobody comes with one of the most published myths of the Emil, the engine-mounted cannon ....

And several other discussion boards with 109/190 experts

The difference between 7.9 and 7.92 mm is small but it IS a difference. Same for "improved MG FF" and MG FF/M.

If you are going to get picky, 7.90mm would be wrong, 7.9mm is a just as accurate way to describe the calibre of the MG17, but not as precise as 7.92mm. BTW 0.02mm is less than 0.001 inches! Is the 7.92mm the diameter of the round, the driving band, the bore, or the diameter to the bottom of the rifling? I mean if we are going to quibble over 0.0008 inches, I think we ought to do it properly[:)]

And the largest difference between the FF, and the FF/M was the /M fired a lighter round at higher velocity... not that big a deal, surely?

Hi Denniss,

I think you meant the E-1/E-3 and why they have been built simultaniously.

Not quite. What I am actually after is the true difference between an E1 vs and E2, E3 and E4 ?

When did an E1 get overstamped to an E3 ? Was it the guns, engine or something else ?

The experten seemed to think that the BMW 601aA was hardly ever fitted. Even then, the performance may not have been as far off of the 601a as first thought.

I am mostly confused. [&:]

The MG FF needed some more modifications to fire the Minengeschoss. It generated less recoil so internal modifications had been needed. Old MG FF ammo was not usable anymore in the FF/M.

Changing the engine did not qualify for an overstamped version number (maybe for DB 601 N but not for A-1/Aa).
The 601Aa had more horsepower but a lower max altitude than the 601A-1 so improved low-alt performance but equal or less med-to-high alt performance (AFAIK smaller diameter blower/charger).
AFAIK E-1 was not overstamped if upgraded to E-3 or E-4 standard unless it was a rebuild airframe. Not sure for E-7 though.

Thanks Denniss,

does that mean an E-1 with wing cannons, stays named as an E-1 then ?

Also, was an E-3 and E-1 that was built with the wing-cannon fit ? Or did they all have the 601aA as some sources state.

E-1 was built with MG, E-3 with cannons. As said abiout 70% of them had the 601A-1, about 30% the Aa. Production of Aa was limited (expensiver to build) so these 30% Aa may have not been from the start but issued to units later. It is very much possible it was issued to JaBos (the /B fighter bomber variants) to have some extra power for carrying bombs and to be as fast as possible over target and back to safe teritorry.

Thanks Denniss,

do you know of a suitable book on the issue ?

I want to learn more.
