ID for a 1941 RAF/RAAF bomb rack

[TacoHombre]

Hi all,

Purchased this assembly at a meet at my local air museum, seller said it was a bomb rack and I was able to confirm through the part prefix, but that's as far as I have gotten.
All searches for "Aerolex" have come up empty, and I'm not sure what to do with most of these numbers on the plate.
Would greatly appreciate some help in identifying this so that I can find any extra info on it for a restoration process.

Ref. 11A/552

11 Bombing Equipment
11A Aircraft Bomb Gear

There should be the DRG number somewhere next to the Ref one as well.

Some dimensions might help but the date appears to be 1941 so I would hazard a guess at Fairey Battle as this is not the standard rack used on the Hudsons and Beauforts.

They used this one
