Here is a quick picture of the CMR Boeing 40B. Not a very good picture- I had the camera on programmed mode rather than aperture priority so the depth of field is zilch :-(
I think I may have found the cabane struts. I thought they were something else- they are the wrong shape. The bottom of the cabanes meet the fuselage in an acute angle. So a locating pin needs to be on the SIDE of the end. CMR has been good on all other struts that meet at such an angle by putting the pins on the side. Not sure if I should drill a hole to put a piece of wire through, or just rely on the glue.
