Back in the late 1970s I'd boght a bundle of the then still in production Britains trees , hedges and walls. I'd added to them in the early 80s during my flirtation with WW2 skirmishing in 54mm. All those assoRted figures and building are now long gone- though there is a photo of one of the games in Mil-mod I think - that we did at NortheRn Militaire one year when I was a member of Durham Wargames Group.
However the trees somehow survived. The dammed things were all in bits and covered in dust , casting talc and not a few spiders but after a couple of days sorting through them I re-assembled most of them. The cold had got to one or two and made the plastic a bit brittle so I lost a couple but once assembled they do look the business and by no means out of place with the 30mm "Shinyloo" British in the photos. I could also of course use them for 40mm
