The guns on Renown's forward shelter deck were 4" low-angle mountings with shields. Those abreast the second funnel were 3" high-angle mountings without shields. By 1926 all were replaced by 4" high-angle mountings without shields.
David, you need to fix Renown's sheerline. The forefunnel should be 6 ft (12 pixels) higher than the aft funnel. She was originally completed with funnels of equal height but the fore funnel was soon raised by 6 ft. There were catwalks between the searchlight platforms on the aft funnel. Perhaps you also ought to lose the second curviature line at the stem and replace the double railings with the correct triple railings.
Otherwise, it's a darn nice drawing.
Are we allowed to use a triple railing?
I used one on my first ship and got smacked down
I'm not exactly sure which curviature line you mean
Otherwise here she is again. The 3" HA has been added at the after funnel which has been reduced and the forward gun is fine.
