Well, they're the first figures I ever owned. They've managed to survive any purges of my collection that headed to eBay and I'm jolly glad they did. They were paint stripped some time ago and put aside for another time, and thanks to the challenge, that time has come far earlier than it otherwise would have.
I think I originally chose them as they were £2.50 for 5 at the time and seemed better value than space marines! Very important when pocket money was a very limited resource.
The grey was the standard colour for imperial guard at the time, the chap with the red helmet is an indulgence as those are the colours I remember painting him in the first place (hey, it was the 80's!) and the colours on the other chap just felt right.
I really like the facial expressions sculpted on them and can easily forgive the slightly wonky proportions (for example, the hands like spatchcocks on the imperial guardsman) and they gave me a real sense of delight to paint them again, remembering doing it first time round. I think the others from the original blister packs are buried in a box in my brother's garage of all places and I just may go and find them now!
