Out of curiosity about Singer machines and production spans, ISMACS serial number data base was reviewed.  It is easy to look up a single serial number, and find model number and allocation date.  I also desired to find more about the history of when model first and last production estimate based on allocations.  The ISMACS data base is multiple .pdf files one for each prefix.  I found opening file and using ctrl F, searching for a model number gives results.  The results are filtered manually, to exclude fields other than model number.

I compiled a spread sheet of date ranges for prefixes.  The ranges help searching.  I hope to expand the spread sheet at time permits.  The left part of sheet shows date ranges, the right is model number research for machines of interest.

that is cool!  Thanks.

Here is a screen shot of my production calculator, also done in Excel
You fill in the top 5 black bordered cells and the rest is all calculated.

I just found ISMACS files are not pdf, but html. I might be able to make an android app.

Thank you for putting this together.

Have you seen http://ismacs.net/singer_sewing_machine_company/model-list/index.html Of course you have to go to different web pages - per your list it would be 3 as VS machines are on the same page as 27 28 15 66 99.

I just reread that page and found "dates are not always reliable and are presented solely as a guide."

I have copies of the ISMACS Singer s/n database converted to .txt files, if anyone would like them.  I find them easier to work with.  (They were created semi-automatically from the original HTML files.)

I have them as PDFs as they were downloaded before ISMACS had it online or directly from Singer. Can't remember. Looks like dated 2011. Think I have a missing one or 2 only in print.
