BAYKO Building Sets Price History

This is a list of the prices of BAYKO building sets, as advertised over the product's lifetime. The primary source for the prices is 'MECCANO Magazine', though some comes from 'Games & Toys', the trade magazine and more from assorted retail fliers, etc. - I'll fill in the gaps as information becomes available.
For consistency, the prices are all shown in the original Shillings and Pence [s/d] format used in the adverts. Prices were not shown in Pounds, Shillings and Pence [£/s/d] until the MECCANO era.
For those of you who don't feel comfortable with the old currency system, I have also produced a separate page showing set prices in the modern decimal format as well.

To put it mildly, the early months of 1959 are chaotic - the writing was clearly on the wall.

MECCANO Era BAYKO Product Codes
I nearly put this information into "Nerds' Corner" but decided against it...
...but I couldn't resist creating a link!
These are the reference codes which MECCANO used in their administration system for various BAYKO sets - including residual Plimpton era stock.

I think it's fair to assume that the 63 within the above codes refers to 1963, so there may well have been [or have been planned for anyway] other models in different years...
