Wanted: 70's French Randonneur Parts (650B rims, 5s Freewheel, etc.)

I am looking for some parts for my Peugeot PX50 from early-mid 70's.
Its a budget project but on-going so please let me know if you have any of these.

1) 650B Rims (or 584 ETRO or 26" x 1 1/2 BUT not 650A or 650C), one matching pair, 36H.

Either Super Champion, Nisi, Wolber or Grand Bois (in other words, double wall type, round smooth top surface classic look) 

3) Randonneur Bar, Alloy, about 450mm wide C-C

4) Mafac Criterium Cantilever shoe clamping bolts+nuts. Hope I can find rust free set.

5) x4 Hangers for Mafac in rust free cond. If you have these bolts+nuts separately thats great but thats rare, so whole set of hanger is fine.

6) Small Hatch/Cover for front steering lock

This bike has steering lock at the joint of head tube and down tube. 
It has small round hatch about half inch diameter in size, similar to oil hole cover you can find in industrial machines. 
Both lock and hatch is gone missing when I bought it and I don't  need the lock but I want the hatch/cover so that rain water will not get  inside the frame.

Thanks!
