Hello Andy,
Your msg. below triggered off in my memory the possibility that the toy shop where your brother got the Blenheim Figures may have been The Toy Tub, a much loved but long departed source of toy soldiers that was in the Stockbridge area in Edinburgh. I know The Toy Tub stocked Britains soldiers and Rose castings, possibly other manufacturers. I just wish I'd bought more figures back then, 30- 40 years ago. I think the business closed up when the owner died, probably 20 plus years back. The other possible source could have been a shop on the High Street/Royal Mile that stocked some toy' in Stockbridge' soldiers but mainly catered for Clansmen Re-enactors and tourists selling replica swords, targes etc. That shop is also long gone, so in Edinburgh one has to rely on the internet or if possible, attendance at toy soldier/military miniature fayres and auction sites. Sadly even on visits to London one can no longer browse and buy in Tradition or at Under Two Flags, though the Guards Shop on Birdcage Walk run buy MKL is still in existence.
"Nostalgia is dangerous and must be avoided." I suspect I am paraphrasing/misquoting somebody with that statement.
