Yea it's a 29.
I like your Idea on color are you thinking of using a solid color Blue or metallic. Think if it was me I would do a solid color blue in a medium to dark blue.
would be fun to paint and add some pin stripes.
Yes stock had straw yellow pin strips on the curved molding that divided the upper body from lower. Stock is two tone blue lighter upper body darker lower but I think it would look better all one colour
