240v 150w G17q A1/182 lamp
 Please note that these projector lamps are virtually impossible to obtain worldwide. The lamp manufacturers made them in response to multiple manuafactures making a range of projectors in the 1970's and 1980's that were designed for these lamp types.
These projectors were not generally manufactured after the 1980's,  at about the same time that the lamp manufacturers ceased making lamps to suit, as to the best of my knowledge, no other light fitting,or projector used these types of lamps.
So, given that no new lamps have been made anywhere  in the world for about thirty years, and they were never that popular, there are very few of these lamps still available for sale anywhere now. I am aware of a very limited number in America, but these are 110 volt lamps, not suitable for 240 volt projectors.  
I have kept this advertisement up in the hope that I may uncover an old estate with one or two good condition unused lamps. But honestly, that situation is becoming less and less likely.
There is no suitable alternatve lamp as they were made for one type of projector only.  There is no adaptor that would permit the use of another type of lamp. 
The only possible options are to have the projector lamp housing professionally modified to accept a readily available lamp. This would envolve making chages to the lamp mount, socket, optics and ventilation. I have done this to several of the smaller projectors I have here, but the time and parts I used in the modification well exceeds the value of the projector.
If you are lookig at purchasing another projector instead, may I suggest the Kodak SAV series. These are an extremely robust, professional type 35mm slide projector with an 80 slide carousel on top. Very good specifications and the great beauty of them is that they use a lamp that is still manufactured, there is absolutely no shortage of them worldwide and at about $15 each, are about a third the price of the blue cap lamps.  
The last option is that you rent a projector. Through our rental side, we have 35 mm projectors available for hire, that may be an option if you just wanted one for  a single night family slide viewing event.
I am sorry that I can't readily assist you with a lamp, but trying to source spare parts for anything electrical or electronic pre 1980 is becoming increasingly difficult. Especially so lamps.
