Rare early projection lamps

Description:

Two early projection light bulbs One, with brass base stand etched on the glass " 367 50 XV 50 The Edison-Swan" and on the other side "Ediswan-focus" with intact filament, turned brass base probably with plaster of paris filling. the second bulb etched on the glass "147 40 XR 32 the Edison-Swan" and on the other side ŁEdiswam-focus" with turned brass base, filling presumably similar to the one above but not visible on this bulb.Filament intact. Both bulbs 10cm diameter. I believe these are very rare projection bulbs from just before or just after the turn of the century. I quote a price for both bulbs but would be prepared to sell them seperately. If you buy several bulbs the postage per bulb is much less. I guarantee to get bulbs to customers intact - or I will refund money in full.
