WTB: Mainly small Campag pista parts - there is a list

I've been pulling parts together for my track build for a few months and i'm nearly there. I just need a few smaller bits to reach the finish line and wondered in anyone on here could help me out with parts/suggestions for parts etc.

1. 3 Campag pista chainring bolts - I have two and see no point in buying another whole set only to be left with two spare again (used or nos)
   
2. 1 C-record dust-cap (used)
   
3. Era correct bar tape in black (nos)
   
4. 80's 1 1/8 pista chain (ideally nos)
   
5. Campag pista lockring (used)
   
6. Campag pista 15t cog (used)
   
7. Campag pista sheriff star rear axle (used)
   
   

Cheers
