NOTES

Turrets and 8-inch mounts are designated as "2-Gun" or "3-Gun" turrets (or mounts) when there is a separate slide for each gun; as "Twin" or "Triple" turrets (or mounts) when two or three guns operate in a single slide. Because of long-established usage, however, all 5-inch and 6-inch mounts with two guns are designated as "Twins."

1-Pdr. and 6-Pdr. mounts, and 3723 Mount Mk. 13 Mod. 0, now obsolete, are omitted from this revision. They may be found in O.P. 1112 (1st Rev.)

Every effort has been made to avoid errors in preparation of O.P. 1112. However, errors and omissions may be discovered in its use. Activities concerned are requested to inform the Bureau of Ordnance promptly of such errors so that they may be corrected.
