RNAS? RAF? FAA of RAF? FRANKENSTEIN?

[Aerowallah]

My first post, and would be glad of any help as all other forums have failed!!!

I know this isn't RNAS, and I've posted my two caps for comparison. But the dimensions, wool, visor and chinstrap are identical to the dress cap. Clearly inside is not of a WW1 pattern. The mystery hat has no stiffener and is of crusher style.

Is this made up or, perhaps, from that rare period 1919-1924 Warren Carroll mentions as still under investigation as to distinctives worn by ex-RNAS? Or is it Fleet Air Arm of the RAF 1924-1937?

Everything is very tightly sewn. Eagle does not appear to have been added recently.

Can't read the whole name.

I tried to collect Gieves labels for dating but all I could find were WW2 which this isn't.

Help and Rgds!
