I just purchased an earlier 29c Double Decker Bus, after previously obtaining a 290 version, with the Dunlop adverts and a later 291 version with the Exide adverts. This new one is obviously older, and having done a little research, there are certainly numerous variations. As most of you are aware, Dinky made 3 basics versions after the war: the first was the old pre- war design, with the original AEC cab, and the rear stairs. Then in 1947-48 Mecanno followed with not one, but two new versions. One was an updated AEC cab and radiator, and the other was a Leyland. From what I have read, Meccano then proceeded to produce both of these versions for many years, and also apparently alternating periods of production for each. How strange that seems, at least to me, and one wonders why they felt that was necessary. The visual differences between the two are certainly there, but fairly minor and not real obvious at first glance.
This model I just purchased is the Leyland without the later adverts. I have posted a few photos of it below, and you can see that it also comes with the later domed axles, has a hole in the baseplate, and has no number cast in. I have been trying to date this model, but seem to find no clear rules for that, other than some generalizations about the different versions. The earlier crimped axles were changed to the domed ones sometime in 1950, and the Dunlop adverts appeared in 1954. That would seem to leave open dates from late 1950 through 1953. I did not see any specific references to the cast-in number of 29c for the Leyland. For the AEC version, I believe it was listed as 1952. Did the Leyland versions follow this as well, or were they never numbered 29c, and just numbered 290 in 1954-55?
If any of you have anything to add, would sure appreciate it. I have looked at the older threads on Talk Model Toys, and also looked at Jacques CD, and elsewhere..............
And finally, here are my 3 double deck buses together
