I'd have to check the model number, but it was Sealey one that I acquired from work after we had several stop working. Turns out the gasket was blowing out on the endplate so the air was bypassing the motor, as it was just a paper gasket on a few mm ridge, so it had little support.

I stripped it, and machined the nose parallel, so it just needs a bush machined so it fits the original electric driver holder.

The problem I had was finding a suitable air gun with an alloy casing and sufficiently long nose section that could be machined straight. Lots of airguns have very short noses, or are now composite bodies.

Actually, just had a look at the catalogue. I think it's GSA02.
I'll cut the handle off to remove some bulk, as it only contains the original regulator (just a basic flow restrictor), and trigger.
Basically everything below the bolt holes isn't needed, and I just need to get air in and out the two slots, and vent the body/bearing.
