At the risk of challenging our knowledgeable and most generous friend Peter, I think the Mk 2 tongs have been misrepresented. There are two camps of opinions, and the technicians have spoken louder than the engineers. The Ordnance departments in Canadaicon and UKicon would not have gone to the trouble to publish two different sets of fabrication drawings if the tongs didn't serve a purpose. However, just about all we know about the tongs is from Peter's point of view.

Everyone agrees that four hands on the scope and one on the rifle are necessary. As I read the drawings, the action of the Mk 2 tongs freezes the lead screw and the disk. That's all. The locking nut can then be loosened or tightened. There is a flat key with 90-deg prongs for that. Peter sketches both in the little green book, and Clive Law has a photo of tongs and a key in "Without Warning". As I read the drawings, the two actions as necessary to confidently turn the scales to line up with the indicator and snug up the locking collar. The tongs replace the tenuous grip on moving parts with several hands for the initial and final steps of zeroing. A controversial tool for two small motions, or perhaps from the other perspective, a way to avoid repeating all the previous adjustments. Therefore, I'd like to borrow someone's tongs to confirm my observation and to advance the body of No.32 scope knowledge.

For the record, the No.4 (T) and No.32 in question held within a 4-inch scoring ring for ten shots at 100yds to get an HPS at a recent milsurp match. It can perform, but the indicator still isn't lined up on Ø.
