Dustettes
Tom, yours are very cute, and I must say the colours on the Canadian model are especially nice. Are both built at Perivale?
Patrick - if yours has a polished nozzle and a black body, it is probably an earlier one, built to match the 700/725 etc. Early ones have a rocker switch, and later versions have the sliding switch.
Seamus - your 100 is very odd - the only blue and grey fixed nozzle models I've seen have been 2504's, with the later squarer handle. I though that and the 2614 replaced the brown & gold 100, but obviously not!
