I've been having "fun" going through all my Boye needle cases to verify the correct needles are inside, and doing some measuring.
I'm not going to post pictures until I can get a macro lenses for my DSLR camera. Hopefully I'll get one today while DH and I are in Sioux Falls. It's really fun comparing the older Boye Displays with the newest one. Like #4, 12, 14 and 21 are all the same "end to needle hole" measure, wide flat shank, and only 14 is on the measuring chart. #4 is the older New Home, #12 is the White VS machines - both of these two groups were pretty much "gone" by the time the newest case came out. #14 is National VS machines, and #21 is older National Rotary machines. The main difference I could see between them the "hole to tip" is different, being 6mm for the 4 and 12, 5mm for the 14 and 4mm for the 21. Now, that is approximate, as Boye tolerances are not that tight. I'll post more after I get home this afternoon -DH told me it's time to go! __________________ CD & SD in SD

I also like to identify needles. Here are a couple that I can't classify...
2.04mm round shank no flat 39.4mm to top of eye 45mm overall lgt stamped Boye"60to80 2.03 round shank with notched end similar to Boye #8 38.9 bottom of notch to top of eye 42mm end of shank to top of eye 47mm overall length stamped victor Any ideas on these two groups ? John

Here are the rest of the Boye set. BTW the first mearsure is based on the Boye Chart, if there are two, first is the older chart and second in the newer chart. NC means not on the chart, NC (xx) means it's not on either chart, and that is the measure from the needle.
Also, when measuring multiple needles, there is minor variation, except the shank diameter, which was pretty consistent +-.01 The shank diameter taken perpendicular to the flat side had the most variations, +-.2 but there are some with much wider flat area than others. Measures are mm
All needles, except were noted have a long grove on the Round side of the needle, with a very short grove at the hole on the opposite side. And when looking sideways, there is no noticeable scarf at the needle hole Boye Shank D D to Flat End to hole Fits Other 2 1.47 1.27 39 Household long grove is on Flat side of needle 2.5 2.02 1.6 nc-32 later Free/New Home Rotary, GE Sewhandy This is the only one with a noticeable scarf 4 2.02 1.45-1.65 NC (38.8) Older New Home hole to tip measures 6mm, 60-80 size needle 6 2.02 1.6 35.45-36 Standard 8 1.41 full round 40 Domestic VS Demorest has a notch at top of needle 10 2.02 1.59 43.8-44 Davis (after Long needle, before they went to 16) 12 2.02 1.51-1.65 nc(38.8) White VS (includes those sold by AG Mason Mfg) hole to tip measures 6mm, 60-80 size needle 14 2.02 1.51-1.7 38.8 National VS Hole to tip measures 5mm, 60-80 size needle 16 2.02 1.6 34.5-34.75 Free/Singer and later White, Davis . . . 18 1.75 1.55 39.85-40 Howe G, WW 9 20 2.02 full round 43-43.5 Davis Old style, White Old style 20.5 2.02 full round 28.75-29 W&G Chainstitch (and copies) Grove goes all the way to top of needle 21 2.02 1.59-1.65 nc(38.8) National Rotary (older) Hole to tip measures 4mm, 60-80 size needle 23 1.03 full round 33 Singer Round Shank (like Model 12) 24 2.02 1.5-1.6 41 New Royal old style, Royal St. Johns 26 2.02 1.89 nc (43.5) American #7 This needle has almost no flat spot 27 1.75 full round nc(39.5) WW #8 __________________ CD & SD in SD

I missread your measurements. I'm sorry for the missinformatiom. Cathy __________________ Most sewing machine problems are the carbon-based unit sitting in the chair in front of the machine. So close to retirement I can taste it. 3 weeks and counting
