Yes, and a year or so ago got the whole series on DVD - still great fun.
I also had an XL5 which you could catapult into the air and it would come down by parachute. I also have some old copies of TV21 the comic and still have the XL5 and Stingray kits you could get for half-a-crown plus so many Zoom wrappers as advertised in TV21.
I have a number of old Dalek annuals as well!
Okay I can remember the following TV series:
Space Patrol (Gamma rays on Yobba rays on!)
Supercar
Fireball XL5
Stingray
Thunderbirds
Joe 90
Captain Scarlet
Am I missing any?
Now the most formative was probably an old Eagle annual which had plans for a small speedboat about a foot long. Built it and the bug bit and the rest is history!!
Cheers
