I was thrilled to find an old carriage lamp for sale at our local St Vincent de Paul shop and grabbed it up before anyone else found it. It looks original to my uneducated eye but I'd like to find out something about its history or age or anything really. There is a coat of arms on the backing board (to do with the patent) but no manufacturer's name. I'd be interested to know if anyone here knows how to trace patents or how to determine the age of the lamp. I taken photos and will post them here once I've downloaded them from my phone. Too tired to take it any further tonight but will be back tomorrow, all being well. In the meantime - please put on those thinking caps. It will be interesting to see where we end up.
