Vintage Gibbons Beer and Ale Ashtrays

I got these beauties at a house sale on 06/22/24. They may be dated from the late 40s-early 50s
Though the red item appears larger, both are of the same dimensions, with 12.2Cm their widest diameters.
They are made of paint on steel.
The red one is the more common ashtray of this series.
Gibbons Beer and Ale can now only be found in Brewery Heaven....
