20x102 link ID help

[lbdrummer3]

Attached is a pic of some odd 20mm links I'm trying to find some info on. I found 2 of these outside of an abandoned aerial gunnery range in the California desert. The range was used from the early 40's until the mid 80's. One of these had a fired steel 20x102 casing in it when I found it which could have been something somebody put together for the heck of it a long long time ago.
Additionally, these things are really difficult to put together and probably just as difficult to separate. What gun system used this link and what aircraft/vehicle use it?

Thanks
Fred

That's awesome Slick, thank you! Do you know if the Mark 11 cannon use 20x110 rounds or 20x102?
I have also found both sized casings in the same area.

Not up on that stuff. Maybe CORNMAN can answer that.

Hi Fred ,

The MK.11 cannon used the same round as the MK.12 , the 20 x 110USN(steel case) ie as fitted to the Skyhawk/crusader etc.
The mk.11 was a twin barrel cannon and was pod mounted.

Cheers

Man, you guys totally rock. Thanks Bob. Are the projectiles for the 20x110 the same as the 20x102? Also, do you know where I could find a dozen 20X110 casings? The ones that I found are heavily corroded and pitted from spending 50+ years buried in the dirt.

Hi ,
Pic from an earlier post.
The projectiles are shorter bodied/more pointed than the 20x102 type.
Plenty of cases in NZ but should be easy enough to find some local to you.

cheers
