BAYKO Set #4 Instruction Manual -
August, 1954 - 1st Issue

This Instruction Manual was produced by Plimpton for their flagship BAYKO set - set #4. Prior to this date, set #4 was sold with two manuals, the sets #0 to #3 manual and the set 3X manual.
This particular issue was the first manual, of any type, to carry Plimpton's new address of Tabley Street, Liverpool 1 on the Front Cover [below]...
Print coded August, 1954 on the rear cover [below], this manual was designated as the 6th issue, however, this cannot be the case : -
Firstly, there were two typesetting errors, relating to 15 x 5 Hole Floors, on pages 7 and 42 [below], corrected with a small Information Slip inserted in the manual [right]. Although not absolutely certain, such typos are usually associated with first editions.

Secondly, the final issue of the sets #0 to #4 manual, contemporary with the MECCANO takeover, is the 4th issue, so it's unlikely that this one was the 6th issue.
Finally, there was a set #3X manual, date coded one month later, which is labelled as the 6th issue of that manual style. I think the confusion between the set #3X and sets #0 to #4 manuals, not unknown even among collectors today, claimed its first victim here.
Information Slips like this [above, right] were used to cover a number of communication needs over the years...
One curious omission from this manual is that there is no mention anywhere, either in the script or models displayed, of the Turrets. I know they weren't included in the set #4, but even so you would have thought they would have rated a mention - they do in the sets #0 to #3 manuals. That means that any child lucky enough to be bought a set #4 outright may never hear of such mythical parts.
There were several versions of this manual during its 5 year life...

...I will eventually try and show all the versions - but this will take a very long time.
