Is it just my imagination, or did Carlton produce an unusually high proportion of five speed bikes? I've seen a lot more Fives than Tens. I know it was very common to find cheaper Raleigh/BSA etc "racers" in Five-speed form, but you'd think a Carlton buyer might have splashed out a little extra for more gears, wouldn't you?
I recently picked up a cheapo project Carlton, and both it and a second Tru-wel donor that was thrown in with it, are both 5-speeders. Nice period Bluemels lightweight mudguards on the donor too.
