For H. M. Navy. Alban's drawings were kept in the same book as those for the Carron [see Portfolio 5/1223]. In Mar. 1832 Alban was being used for Channel and harbour services. In late 1838 it was intended to fit the Alban with 50 horse engines removed from the Carron, but this plan was never carried out. Alban's engines were however later increased to 50 horse power. She was broken up in 1860. |
