Many thanks to all for your responses.
is structurally sound. I plan to strip the paint
, repair a worn-through spot on the top of the gunnel and then repaint. However, my purpose in trying to ID the manufacturer; it appears there was a rubrail or trim piece on the top of the gunnel (evidenced by the unfinished fg matting, and holes evenly spaced that were obvious attachment points for the trim). Anyone have any ideas on how to find suitable material to replace that trim?
The top of the gunnel is rounded, which would indicate the missing trim had a rounded base that neatly fit/conformed to the shape of the top edge.
