what is the 3 Pdr AT gun?

However there is no evidence for a towed ATG with the same weapon.

The main reason for making this query.
Nor have I found any formal AT gun prior to the 2 pounder AT gun for UK and ANZAC.

It is though in the UK, Canadian, Indian and ANZAC OOB.

Is it to stay or vanish ?

It will be going, and the pick list will change for ATG formations in the 30s.
