Thank you Paul - that photograph is the most detailed one I've seen yet. I'm almost scared to mention this as it shows what a "rivet counter" I've become - its a front wheel.
And how do I come to that conclusion - I know front wheels had 10 spokes and rears had 12. What I didn't know was the wheel(s) had a metal inner & outer bands - I live & learn!
Registering on your site has already proved itself to have been a worthwhile exercise - thank you.
