OT, but related, sort-of. Omark 44

[Bruce_in_Oz]

Just scored a couple of barrels for the Omark 44. Old-style, integral locking lugs and all.

Both came out of waxed paper wrappers and appear to unused.Interestingly, the Lithgow-made, hammer-forged Black Mountain tube is about an inch shorter than the "Sportco / Omark one

Does anyone have any record of the twist rates and how, if at all, that might be marked on these barrel.

I know early barrels were 1:14 inch, RH, but that changed to 1:12" at some time.

A couple of "revival projects" await. One of these is intended for FTR competition ("Poverty-Pack division) and thus may end up being fed longer, "VLD" style bullets which may not like a 1:14" twist, even from a 27" barrel.

Any thoughts?
