Woody,

I have played these 'guess the parts' games in the past and made a arse of myself...what the heck, here goes! headscratch

I can't really tell the scale, and don't know if all the stuff is related, but could it be steering column parts. That spring looks like the one near the upper mast bushing. You don't see SAE fasteners in most places on these old rigs.
