Interesting little item, face square is only 15 cm and has strike and alarm as well. It has been converted with an arch but original only a very small square dial. No signs of ever having had side-doors, nor pinnacles and backplate. Not ever has spikes and a hanging loop. The lantern clkock type movement is very nicely made with well cut wheels and the dial is signed D.Robinson London. It all looks quite early as far as I can see. Thee case has been made much later when the arch was attached to the dial. But what could this have been originally Seems to small for a longcase movement, but does not look like a lantern as well?
