The most memorable/best was a Panther Tank, i think a Monogram kit during the 50's.
This was the time when Airfix was king of the roost and there 1:78 scale stuff lined the shelves of model shops. The Monogram kits were only available in "selected stores" and where about 4 times as big as the 78 scale stuff so, maybe 1:35 scale? i really cannot remember.
What was amazing at the time was the grey-coloured plyable tracks that came with the kit, for the first time you had the impression that the model would 'roll', and the level of detail was superb for the time.
I used to visit my grandmother in Coventry during the summer holidays and found a model shop near the old cathedral, in Gosford street. This place was a true revelation and i used to stand in front of their window just looking (gawking would be more precise) at the models.
Some were huge for the time, items like the 155cm? cannon from a kit maker called "Adams Action Models", this was top of my wish list for ages but models were very expensive in those days (relatively speaking) and i knew even then that it was nothing more than a dream. They also stocked stuff imported from America such as the Monogram range and they all just so much bigger than the home grown stuff, absolute heaven for small boys then, even though it would be regarded as 'small' these days.
The choice was staggering for the time, planes, boats, cars and military vehicles, all plastic kits, then the bigger stuff such as Keil craft planes to make and fly, i felt like i had discovered the end of the rainbow. Funnily enough, i cannot remember ever going inside but he memory of that window is still as strong as ever.
