Measurements of 1/72 Defiant turret?

[RotorheadTX]

Just a quick favor to ask - does anyone out there have an Airfix Defiant, or other similar turret fighter?
I'd like to know the height (with glazing) and diameter at base in 1/72 of a Boulton-Paul-type quad-303 turret, with an eye to plonking it onto a different airframe.

TIA,
Tony

Don't use the Airfix one as a marker as it's decidedly inaccurate.

Let me elaborate then... I want a BP turret to stick on a TBM/TBF Avenger/Tarpon.
Kit-provided .50cal turret is 16mm across the base of the bubble and roughly 13mm tall.
Recommendations??

The four gun turret on top of the Halifax was supposed to be the same turret the Defiant used, maybe you can use that one.

If you are set on using the airfix one, bare with me.. Bits of the Airfix defiant including the turret are in my bits bin... I'll have to find it out for ya at the weekend..

The Airfix turret is 13mm base diameter, about 6mm from base of glazing to top, NOT including the rim (which is about 1mm).

Have you thought about using a Martin turret?

Weaver, thanks for the measurements - a bit too small indeed. Drat!

Dogsbody, I didn't know they had tried the Martin turret, that steals a little of my thunder. Double-drat!

Tony,

have a look

I used the base of the kit turret, and a circle of plasticard to match the turret glazing diameter glued on, then good old PSR.
Once it was all dry cut out the middle of the circle ( I have a Dremel so that bit was easy) to give space for the gunner and guns.
Then the glazing gets plonked on top

The Turret used in the Defiant was the Bolton Paul A type Mk IID and the version used in the Halifax was the A type Mk VIII. I could give you lots of info on the A type from "British Aircraft Armament, Vol1 RAF Gun Turrets From 1914 to the Present Day" by R Wallace Clarke. However most of the turrets do not have all the information us modellers would like, such as Hight and diameter of the turret. One of the turrets that does have such information in the book is the 20mm turret which was used in the Lincoln and Shackleton. If that would help let me know and I will dig out the info for you.

Thanks kindly to all, especially Jim, that's just what I had in mind!!
