Chain rub issue on Gran sport rear mech ?

[bagpuss]

Minor issue of chain rub on a steel gran sport rear mech circa 1960's.
Cage appears to be straight {Purchased as NOS}, plates for holding jockey wheels are not bent and bolts are tight and the right way round . Chain line appears to be correct .
Chain rub is worst between 3,2,1
spot on on 4 slight rub on 5 .
The chain is catching the plate nearest to the main body of the mech itself .
5 speed block {NOS} used . Chain is also a nos renolds derailer type and right pitch / size. Bolt to rear hanger is tight .

Any pointers welcome .

Are they the right jockey wheels?.........too thin?

Early ish campag rear mechs had acres of space between the cage and the jockey wheels.

Any pics?

Hmm . Beginning to think the width of the chain is wrong .Sure it was 1/2 by 3/32 :?

Gear hanger I assume on the frame is straight & aligned?
