You have an Armstrong mast. @Manu has designed this pod for a Gong V2 alu mast. The files are available here on thingiverse: New foil gong for the end of April - #23 by Manu
@jeffM adapted his Fusion files to a Gong carbon mast. You can find Jeff’s files in this thread Gong Carbon Mast Clamp
Maybe the next step will be toolless on an Armstrong mast 
?
