Thanks for these, some data I've missed or incorrectly known (For example Design 612 I've set the pp length as oa length. (Friedman rarely states which length is which.... )

Hmm...
4"/45 Tertiary guns...
At this time, 1908-09 neither the RN or Vickers produced such guns.
The first 4"/45 for the RN was the QF Mark V of 1913
For Vickers that was the Mark K from around 1919.
Armstrong at this time had the
Pattern M of /40 calibre (1907)
Pattern P of /50 calibre (1911)
could this /45 gun be actually the 100mm/44 Pattern N (1910)?
There was possibly a Pattern O gun but I have no data about it.

Frankly I would not know what exact model of 4 inch cannon.

By January 1910 it was determined that the gun would be the 4 "/ 50 Bethlehem by these characteristics:
- 15 kilogram projectiles, initial velocity of 914 meters per second and rate of fire of 12 rounds per minute.
- The artillery and its ammunition would have to be interchangeable with the 12 (to 16) destroyers to build.

The model purchased is practically identical to the Mark 9 from the United States.

Similar requirements will have been exposed to British houses in previous months.
In Vickers' offering with his Design 428 (before October 1909) the sketch of these guns is exposed.

And according to Friedman it would be semi-automatic.
