As with yours, it still has it's linnen lining, a fair amount of rubberization (by the feel of it) labels, bunny suit etc.
Unfortunately it's a size 3, so I'd be hard pressed (literaly) to get into it.
Some of the zips are U/S, but given the materials used that's hardly surprising; a lot zips crumble to the touch.
All in all a very nice suit with just the normal staining. A good honest used Sidcot. I love the greenish colour!
i also have a 41 pattern Sidcot in good nick, but I don't really like the colour (too dark), nor the studs for the heating system.
It's a size 7 though (with a brand new kapok liner) so I can wear it if I ever get to flying open aeroplanes
As my 30 pattern Sidcot feels quite brittle I wouldn't want to wear it.
I'm still toying with the idea of making a repro in the right light green colour, but made out of Nomex (for safety)! Wouldn't that be something?
