It's always nice to come across something that you had half forgotten about. Rummaging in the stash at the back of my loft this afternoon I uncovered three mint condition Airfix 'classics', which I may now press into use. I probably bought these 20+ years ago and the price labels are still on the boxes: the Waterloo farmhouse is £7.99 and the other two are £5.99 each.
I also have a built Waterloo farmhouse which I will now 'recover' and re-work, completing the empty doors and windows that i was too lazy to model properly when I build this back in 1980.
Happy days.
