WWII Escape Buttons

[Truebrit]

I am relatively new to the forum, but have seen a few threads on WWII Escape buttons. I am a collector of such items, so if it's permitted to canvass for items, I'd always be interested in items for sale...

But my reason for posting, is to ask any members who collect, or have come across E&E buttons, or have friends who collect, what types of buttons have they come across - I mean as in different Regiments and Corps, since there are no surviving records of this.

To date and in over 12 years of collecting, I have seen only One individual Regimental button (Royal Berkshire Regiment). But below is a list of what buttons I know of, but I'd really like to hear from members with any validated types beyond these - all the better with a photo:

Royal Artillery
Reconnaissance Corps
General Service button
Royal Air Force
RNZAF
RCAF
Polish Air Force
USAAF
Australian Armed Forces
New Zealand Armed Forces
British Staff Officer's button
Royal Navy
Royal Marines

So please reply with any types of buttons which you hav verified beyond those above, as I'd love to try to build a definitive list - as best we can this long after their production and use...

Many thanks everyone
Phil
