What is this??

Thanks for the replies , so I think we have established that it is a no. 27 gun limber axle that should be on 9.00x 16 rims , threads on the wheel nuts appear to be BSF , as my Canadian ones off the Lynx don't screw on.
The rims in the pic are 20 inch CMP rims , I must have had a brain fade on the rims ,because I have a rear engine armoured car that uses these. Anybody out there restoring one of these Limbers ? Cheers.

Andrew, brain fade at your age. You're on the way to being a SOB (silly old buggar)
I thought the small CMP wheel studs had BSF threads.
