Hi Stan,
Unfortunately Wonderland is a shadow of what it was and there are so few proper model shops in Scotland now, it's widely known as a box shifter / toy store now. It's not what it used to be by a very long way. Harborn Hobbies on Leith Walk is also well worth a visit but the price of railway, particularly N-Gauge is just eye-watering these days compared to 10 years or so ago.
I was repeated statement today I originally heard from a sales guy in Wonderland a few years ago " we don't to parts, they're all supplied with the kits" -it's a sad state of affairs.
...I was trying to find an R/C model shop in the central belt of Scotland today and having driven over 100 miles and spoken to places in-between just about the only place worth visiting now is the Sports and Model Shop in Dingwall, 10 miles from my own home!
It's a sad but very real truth the hobby is very much dying in Scotland the past couple of decades. There are literally just a few traditional model shops left now in the whole country.
A for East fortune Its a fair trek out from Edinburgh. Concorde is there also though. My late father developed some of the original engineering panel simulators for it when he graduated -I took him to see that Concorde years ago in East Fortune and when we could squeeze the guide out of the cockpit, he could still remember what most of the dials were and what switch did what on the engineers panel.
