I have an old wooden boat model that needs your help. This model was handed down to me many years ago by my uncle who it served in the US Navy in World War II. If I remember correctly the label on the bottom had a date of the 1800s that has since faded away. I know that my father had replaced the canvas, Using the old sales for patterns, and lines years ago, however the mainmast and yard have broken off over the years in storage and it is in disrepair and needs some work. I would appreciate advice on whether I should repair or replace the mast and yardarm, also not so sure that the rigging was done correctly. The nails are all original and, as I remember, my father added the black rung portions of the rat lines. Thanks in advance for any help. Incidentally, my father was a custom tailor and used standard sewing thread for all rigging. Not sure if it is acceptable.
