X-K-3136 Chain Guard Rear Screw 5/16-24 x 1.1/32
G-6388 Chain Guard Rear Bolt Spacer
So definitely a spacer on this one!

Hope that all helps - as I said at the beginning, it's my interpretation and may not be 100% correct! If any further details are required please let me know
Bye for now - Steve

my 1920 chainguard is a bit broken, anyone able to post piccies on how they should be joined, ie top bolts to a hole in the crankcase and to the frame towards the rear, assume the bottom attaches to the top, there's a rear point intact but front is a bit hacked about. pic is of bike, will post pics of guard in another post
