[emeritus]

I still have my mum's old pink MR hairdryer like the one in the middle photo in the original post that got made redundant after she bought a later model with hose, head cap, and continuously adjustable heat, from memory, effected by a mechanical baffle that mixed the proportions of heated and unheated air. The original one did start glowing brightly at one time sufficient to start charring the plastic of the nozzle, but that was fixed by cleaning out the build-up of charred fluff from the element that had been restricting the air flow. I use it to gently warm broken items that I have mended with Araldite to shorten the cure time.
