the manuels contained on the hnsa web site is for the twin mount but can also be used for the single mount because all the twin mounts are is two singles bolted together with through bolts. just see if you have the mark1 or mark 2 for any parts you need basicly the left gun or right gun there should be a data plate on the breach block.
also if any body out there are looking for orlicons or bofors turkey and greece are just now starting to decom the destroyers we sold them in the 60's.
