RAF OA Blue Shirts,different types,styles???

[Scotch Harry]

Please excuse my ignorance but know very little about RAF clothing etc as my main interest being the Army side of things.

 

Recently bought a small job lot of RAF items that were believed to be issued to the same person which included various shirts etc(all believed to be lats 60s/70s issue)and there are 3 blue shirts of 3 distinctively different styles(will take and post pics as soon as I can).

 

 

1 type labelled as SHIRT,MANS(blue collar attached)RAF

 

1 type labelled as,no designation just a makers name and number of 22B/9424861

 

1 type labelled SHIRT MANS BLUE GREY RAF

 

Thanks
