I have several envelopes of organ needles. What does all the information listed on back of envelope refer to. I recognize the size of the needles but what about the other information. Example is HAx1 130/705H 15x1. Thank you in advance.

If you can google for their website or info on line, you can probably ask there! I found this on Etsy.

Those are different "systems" of needles, but all are the same dimensions of flat shank, total length of needle and length from the top to the eye of the needle. I believe HAx1 is Japanese, 130/705H is metric/European and 15x1 is Singer. These are the systems used for most domestic sewing machines.

There are a very large number of systems, especially now with industrial, sergers and embroidery machines.There were even a variety of systems in the early days of sewing machines. It seems like many manufacturers used proprietary dimensions of needles for their machines.
