I've been interested in London Buses most of my life and have a substantial collection of the various models. However the EFE RT1692 model reg.KXW337 leaves me with unanswered questions. It is shown with no roof and working on service J which was during the 1951 Festival of Britain. I know RT1692 was one of a few buses that went abroad with GB plates but have no proof the roof was ever taken off. Also the model has the wrong reg. plate as I am certain it should be KXW338. So could it be KXW337 is actually another RT which did have the roof removed. Any positive answers would be welcome.

Simple answer is the early EFE models are not accurate depictions of real buses. Few of the buses depicted, RMs & RTs, depicted actual buses that operated on the routes depicted or in the correct colour in one case.
The other open top non LT RTs are also fictitious.

The EFE Zone website explains many of the early errors or you could look at/join one the Facebook groups that specialise in LT models.
If your model has the wrong registration plate then it's been applied after purchase and not new. None of the depictions of RT 1692 had number plates fitted!

My bus number (if any): RTL 960, RMC 1458, RM 1585 and several RTs
