RFI: Mk. I gun pod.

[CostasTT]

Hello everyone!
I'd like to know where I can find some information regarding the twin 0.50" gun pod seen mostly on SB2C Helldivers and also occasionally on F8F-1 Bearcats and on an experimental P-38 (armament test bed).
I know it's called the Mk.I, but so far this is all the information I've been able to find about it.
What I'd really like to know is data such as size, weight, ammunition capacity and stuff like that.
Here it's seen on a RHAF Curtiss SB2C-5 Helldiver in 1949.

Thank you all in advance,
Costas

Costas, on the China Lake site there's a picture of a Helldiver with gun pods, identifying them as "Harvey gun pods." (link) I wonder if these are the same pod?

 

[CostasTT]

Definitely not, I checked. The Harvey pod has a single gun.
But thanks anyway.
Here are a couple more of the Harvey from China Lake, as well as a pic of a Skyraider with AAFFR gun pods.

More on the Mk. I gun pod.

Here you can see two pods on an F8F-1.
And here on a P-51B.
