Max yes they were built in Marysville Wa and were very popular. In their day they seemed to be everywhere in SE Alaska. In Juneau, Angoon and most everywhere else. A good looking boat too .... much better looking than the aluminum boats that replaced them.
Like all older FG boats many to most have rotten stringers in their hull. 2 x 4, 6, 8 ect were the major structural members running fore and aft along the bottom of the inside these hulls. One can repair them or replace them w non-rotting material but it's a big job.
