Could overseas bases reline Pom-Pom barrels?

Did Britain try to establish overseas workshops that could reline worn gun barrels?

Yes, but early-war bases could handle only part of the work, so many barrels still had to return to Britain until heavier overseas facilities were available.

Some overseas facilities could perform ordinary gun maintenance, and additional workshops were planned or established later in the war. Early schedules had assumed the major conflict would begin around 1942, so much of the specialized capacity had not yet reached bases such as Malta or Alexandria. Relining required heating the barrel, removing the old liner, and installing a new one with machinery beyond an ordinary ship workshop. The shortfall was compounded by the interwar closure of British factories that made the machine tools needed to expand such facilities.
