Daimler D 18 Special Sports 1939/40? Body maybe by Barker.

Not a Daimler

Could this be a late 1930s Humber Snipe?

The wheels look right, and there's a dangerous-looking pointed mascot on the front that would also fit.

[Otto Puzzell]

Not a Humber.

Vauxhall?

[Otto Puzzell]

Yes!

[woodinsight]

I think it must be a Vauxhall Big Six cabriolet of the period 1934-1936.
The other large Vauxhall - the 25 - featured steel wheels not wires.
The body is very similar to that of the Barker-bodied Daimler I mentioned earlier.

[Otto Puzzell]

Right you are.
