Odd gunner button

Sorry, haven't the technology to put a photo up, but have been given a button to identify.

It's flattish (rather than ball) button, approx 7/8" diameter, with crown and gun, 12 spokes on the wheel. Old looking, brass colour but too light?

Gun is not surmounted by Ubique, nor by H.A.C.

There is a motto underneath but I cannot read it.

The trail of the gun is on the right, barrel facing left, parallel to ground.

Diagonally through the wheel, maybe resting on axle, is a rammer (sponger, or suchlike?). This has at each end what might be a coil of rope proud of the shaft. The highest part of this sits as high as the head-band of the crown.

 

Some of the gunner Regiments (like the HAC) had their own motto on the badge. For example:

 

In WW 1 there were three different branches of Artillery, these were The Royal Horse Artillery,The Royal Field Artillery, and The Royal Garrison Artillery, plus the HAC, And as Ravers has said units had modified their badges, the Badge shown by Ravers is of the Hants volunteer RGA who would have in peace time manned the heavy guns installed in the coastal defence forts( Palmerston's Folly) in the county

These units were also armed differently, the RHA had 13 pounder guns, meant to support cavalry, the RFA had 18 pounder guns and 4,5 inch Howitzers, and the RGA had 60 pounders up to 15 inch railway guns

 

Old or new? It could be staybrite. It sounds like it should be the same size as a SD/no2 dress button, although without running upstairs, I don't think they have the motto beneath the gun.
