I got my great looking spur adaptor last week. Thanks Mike! I installed it on my new DM-1 instead of the gtp. It just took another flat spot on the spool shaft to line up with the pinion.
I also used it as a 36t pinion with a rcm 8mm-5mm sleeve on my XO-1's 1717.
I might get another one because they are so versatile for me.
