For starters. the Pullman & Observation cars were #629 and 630, not 229 and 230. As Tjcruiser has stated, the transformers were not included in any Set in that time frame. The ones he posted, are most likely what you could have used. As far as the contents of Set 292, it would have been Red 248, Red Pullman & Observation, 068 Warning Signal, and 8 curve track. The price in the 1927-1932 was $7.00 for the complete set. If you have all the components, and the box, the price listed from McEntarfer's Sets, lists it at $350. Hope this answers your question.
