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!

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 ?

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
