Wheatstone Ledgers

[gavdav]

Hello - I'm looking at my concertinas in the Wheatstone ledger. I understand the date, model description and serial number columns - what do the other two columns indicate? Is the first column model number? Do the diagonal lines indicate that the gaps are filled by identically specced models? I am looking at this page:

thanks in advance

Gav,

Yes, model # to the right of the date. Anything within the field of the diagonal is a similarly appointed instrument.

 

To find the model # descriptions consult the price lists that are found under particular concertina systems at concertina.com

Thanks Greg - what about the number after the descript. but before the serial?

I have just looked inside my concertinas and those numbers are stamped inside like Jeffries batch numbers - so I'm guessing something like a code to make sure parts all go together. Interestingly they're not in sequence, nor are parts interchangeable between identical models, unless these numbers mean something else. It is also interesting that they're inked inside the concertina with a stamp rather than written. Any thoughts?
