20 X 110 Hispano representing SAPI

[Robert B.]

Good timing with this thread - found a 20mm round in the flea market today, 'BBC 1942 20mm' - didn't buy it though as it had been made into a lighter with a false projectile that slid off the shell...

I think most of the problems would have been overcome had more time been given. The technology improved considerably between the mid 1950s and when the GAU series of aluminium cases were developed (1970 ish?).

The committee said that 30 mm had reached a stage where it was promising, but there were still problems that if the cases got scratched or scored in handling, a burst case was likely to result.

I have (poor) photocopies of the photo of the 30/20 light alloy case if you would like me to post.

Yes please Tony I'd like to see the photocopy.
Ta,

Steady Young Dave, steady!

I could show you the drawing for the 30mm Aden LV aluminium case, but I would not want you to have a seizure on my account!

Tony I've already had a seizure looking at the 30/20 aluminium one.
Attached are a few of the other types I have. The HV and LV aluminium cases.
