I was always rather envious of FMC Dove's wind-up gramophone, used to such good effect to accompany their videos of the Braunston parade, and generally create a suitable atmosphere at historic boat gatherings... I never thought I would find one for Chertsey, at least not one in working order at an affordable price. But as you can probably guess, given that I'm writing this, I did. It was in the window of the antiques shop in Penkridge, and we bought it for ninety pounds, complete with a 78 of 'Polly Perkins from Paddington Green'.
It does work remarkably well - and it's loud! with no volume control. As you can see, it doesn't have a horn - it is in fact one of the last and best wind-up gramophones made, the HMV 130 table top model (so not really intended to be portable) of which thousands were sold well into the 1930s.
