It may well be from ROF Poole but I was simply elaborating on that fact in that it was also, in my opinion, judging from the sloppy paint, ex Indian Army too. I realise that you didn't actually ASK this Promo, but being a kindly fellow and eager to please, I offered it anyway
Here's another suggestion that you might (or might not, depending on your point of view....) appreciate. Another way to ascertain a realistic value is to look what the various traders have to offer, deduct 30% or whatever you consider to be a dealers mark-up and use that figure as your ball park or what we in Englandcall 'mates rates'
