I doubt they made a lot of extras, Marston had a very "modern" production facility they even did time & motion studies on the component production, these included fettling time, sorry nothing on the cylinders.
The costs of machining a bare casting to a finished cylinder were considerable & putting 50 on the shelf might well have taken them out of the profit side of the line into the loss side, in their new outboard division.
And I can't belive British Seagull when they took over, would want to keep spares on the shelf that didn't fit any of their product range, more likley in the middle of a major resession they would assemble as many motors they could from the Marston spares holding, to get some money try to recoup some of their investment.
Make it idiot proof and someone will make a better idiot.
