Cap badge of woman driver (possibly?) 1918-1922

[MBrockway]

Can anyone help myself and Drew-1918 (from the Great War Forum) with a cap badge and uniform puzzler?

This photo dates from approx 1918-1921. We are not certain whether it was taken in the UK or in France/Flanders, or even in the Rhineland.

It shows a woman in uniform, possibly a driver in one of the auxiliary forces, but it could also be one of those posed Sweetheart in uniform portraits one sometimes sees.

The puttees and boots counter the possibility of a civilian bus driver role or similar.

The jacket appears to be 'patrol' style with scalloped breast pockets and a sewn in cloth waist belt, but lacking epaulettes and shoulder patches. Difficult to be sure of the jacket's colour, but it does not seem to be khaki SD with a much finer surface finish.

The upper surface of the hat visor is glossy.

Other than the cap badge and possibly the buttons, there is no sign of any insignia, nor of brassards etc.

There is nothing useful written on the reverse nor in the section of the image I have cropped off.

I've done some close-ups of the head and the cap bage. The latter is also presented with the colour inverted - sometimes this helps with the badge shape.

Does anyone have any idea what this lady's role and unit might be?



All help welcome!
