Years ago (late 60's to the early 70's), I used to go down to my local hobby store and buy an Airfix kit on every saturday. I spend a few hours building it, then I'd spend the rest of the week playing around with it until saturday came again.
For the past four weeks, I've been doing (more or less) the same again. Every Friday, I go down to the same hobby store (It's still there folks!), buy some old series zero Aifix kit, spend a week building and painting it, until friday comes along again.
After around twenty years of buying quality kits, accurising and painting them, I have to know if I'm going senile.
