I've got an old basha in need of some tlc which i'm pretty sure is the same as this one - http://www.greenmanbushcraft.co.uk/...live-green-lightweight-british-army-basha.htm - as the weight and dimensions are exactly the same (640 gms). There's a couple of pin holes and some small 1cm rips in it that need fixing & i was all set up to use some regular Mcnett seamgrip on it, but i came across an old post that seemed to suggest that it is silnylon and not pu coated nylon. If so, i'd be better off getting some silnylon seamsealer, so i'd be grateful if anyone could tell me which it is - silnylon or pu coated nylon? Many thanks if you can help.
