Folks:
When I was a kid in the 1950s, before I ever smoked, I used to notice the different smells of all the brands of balsa cement you could get then. In England, the ones I remember buying were KeilKraft, Lepage's, FROG Universal, Joy-Plane, O'My, HMG and the daddy of them all, Britfix. This came in a tube with very fancy printing on it in several colours, and the smell... it was just like apples that were very ripe, almost overripe - utterly delightful. Then Britfix disappeared and was replaced by Humbrol, which smelt just the same as most of the others. A pity.
Happy New Year
John
