Seeking dimensioned drawings of the Hispano HS.404 20 mm cannon

[Model_Monkey]

Seeking dimensioned drawings for both the Mk.I drum-fed cannon (Beaufighter, Whirlwind) and the Mk.II belt-fed cannon (Spitfire, Hurricane, Typhoon, Tempest, Mosquito, Beaufighter, etc.).

 

I have scanned copies of US Army technical manuals TM 9-227 and TM 9-1227 from 1942 which have excellent, detailed photos of a nearly identical US version of the gun and all of its component parts, but nothing is dimensioned.  I know what the components look like but not how big anything is.

 

Any help is hugely appreciated.

Hi, Just got a copy of the RAF Museum re-print of British Aircraft Guns of WW2 plenty pictures but no dimensions.

But just drop Arthur Bentley a line I'm sure he can sort you out all his drawings are top notch !!

Thanks so much, Bob.  

 

A.L. Bentley drawings are truly sublime.  Unfortunately, shipping just the one piece of paper to the US costs £30 (over $40 USD).  I'll need to keep looking.

 

Thanks again.

I thought ALB did some of his drawings via electronic media vs paper?

I will contact Mr. Bentley and ask.

 

Cheers!
