Product Description
Carriage lamps for the Pintsch-gas system: set of 20.
Pintsch gas, a petroleum product, is the fuel for the lighting system developed by Julius Pintsch, which superseded coal-gas lighting for railway carriages. Most British railways used Pintsch gas for lighting and some of them (notably the GER) bought the lighting equipment from Mr. Pintsch's company.
The current model represents a lamp that is certainly for burning Pintsch gas and may also be a Pintsch product, this latter point being unconfirmed. It is based on the dimensioned drawing of a gas lamp used by the London Transport museum for product of full-size, replica lamps. That drawing, in turn, seems to be based on an engraving of a lamp. This kind of lamp is therefore presumed to be correct for Metropolitan coaches and, based an outline history of GER coaches by the GERS, and on a contemporary photograph, seems to be right for at least some GER coaches. Please note, however, that the surviving GER coaches at the East Angian Railway Museum have slightly different lamps; these may well be later fittings. The model might also represent the lamp designs of other companies, but buyers should make their own comparisons with drawings and photographs.
The model represents the cover and chimney of the lamp, as visible outside the coach, plus the lamp glass visible inside the compartment. To mount the model, drill the coach roof 3mm diameter (4mm scale) or 5mm (7mm scale) to admit the lamp glass and the slight flange of the lamp above the glass should then rest on the outside of the roof. Please note that this flange is curved slightly to follow the curve of the roof (8' radius). To align the curved flange, note the small, horizontal hole in the base of the lamp. This is present to admit the gas pipe (modelled at 0.5mm; drill it out to suit your preferred piping-material) and should face at 90 degrees to the axis of the coach.
The original drawing and engraving show the lateral feed-pipe running to a block of some kind that mounts onto the carriage roof. I suspect that this is a regulating valve to reduce the pressure in the main pipe down to that needed by the lamp, and that the circle by the base of the block is the cross-section of the high-pressure feed-pipe running down the length of the coach. I have insufficient information to interpret the drawing reliably and therefore have not included this fitting in the model. If anybody can supply better pictures of the feed arrangement, then I will consider adding it.
