As Ron stated it is 14 tpi Whitworth form.
For 2" Guage, which was the standard and also 14 tpi Whitworth form. -
Major diameter - High 2.003", Low 1.997"
Minor diameter - High 1.912", Low 1.906"
In the absence of any drawings, I would suggest subtracting .4 from the above.

I have a fuse plug for the 76mm HE ARMDC. That should be perfect. It is a good thing I stopped boring at 1.536 inches. It will be a little large, but it will still thread. Do the L17, No. 244 and No. 256 fuses have the same external dimensions? Thank you.

May I request a drawing showing the dimensions of a 17 pdr APCBC projectile? I do not have one, and I have an order to make six resin reproductions for a chap in the US who has an Achilles M10 tank destroyer. I do have an AP shot that I can use for most of the dimensions. What I need to know most is the length of the projectile and length of the piercing cap/ballistic cap. Thank you for your help.

Here is a 17 pounder case that just sold on ebay in the US for almost $450. Interesting, I was selling 17 pounder cases in the US over a year ago, and I could not find anyone willing to pay $200. However, it is marked as a No. 2, and it has no crimp on the neck. That makes it an APDS case by my understanding. Canadian made also - I believe.
