Ok, you really have been looking closely! My fault, i failed to put it in the pic - apologies. Although the seat bolt is also missing - this is the one item which i could not remove with allen keys and had to be cut out - not necessarily because of rust, the bolt was too worn inside for the tool to get a purchase - my fault 20 years ago and not Raleigh's.
Thanks for taking the time to read this - i hope to get the bike running within a week.
My only difficulty with the 'back to new' restoration is the wheels - it will take me some time to get them rebuilt probably after Christmas but i have the ones in the pics to get the bike on the road.
Thanks all
