I'm restoring a 1941 Old Town Yankee and am finding a number of steel tacks and nails. Mostly attaching the planking to the stems and the ribs to the inwales. The build was started in October of 1941 and finished in July of 42 according to the work order. I'm wondering if the war had anything to do with the steel used - brass and copper in short supply? Anybody else run into this issue? Thanks.
