Great!!! At last contact with sentient life out there...
I have had it for 30 years. It looks vintage 30s or even 20s. The lady who sold e it was most disappointed I only wanted a vacuum cleaner ... and the paltry offer. Seems like a quality piece of kit, strictly 'Upstairs'
But with her in mind I have looked after it quite well. It's a hand held, very similar to the Goblin in a later episode of the second series of "You Rang M'Lord?"
Here it is . . .
