Nose Tank technical question

[VictorBravo]

Can anyone verify for me whether the shape of the nose tank is different on the pre-war B model airplanes compared to the post-war B model airplanes?

Could the lower part of the tank have a steeper slope on the later airplanes?

This would explain a LOT about the previous engine issues I've been having. If the pre-war tanks have a shallower slope, then on takeoff acceleration the head pressure would be less than a post-war tank with a steeper slope.

Having seen both a pre-war terne-plate tank and a post-war aluminium one, I'd have to say they were the same.

Only the drawing (or a direct measuring comparison) would confirm it.

Anecdotally, I can not see why the basic shape would have changed. The width & length are both constrained by fitting within the steel tube forward fuselage frame, and they are both 12 USG, with apparently the same firewall exit point, so I can not see an alteration to the height (the only remaining dimension available to change) being different.

They are the same except material differences.

They are the same ..... drawings show this.
