Thank you William for the help, I'm very grateful! It's always a great pleasure to learn something new about our hobby, especially when a newbie in this area (British/Scottish/Commonwealth) military like myself!
One dealer/collector in UK already told me that this could be from the 1950's For his defense, he's involved with WW2 era stuff.
I must say that British/Commonwealth uniforms/headgear are fascinating, especially due regimental level dress code differences! I think I'll dig deeper into this...can't help it!
I already sent a message to the seller that I'll take it... I hope he still had it!
Will keep you posted !
Thanks again,
Miikka
