Found some NOS Campagnolo white hood rubbers so they are now on the bars for the Holdsworth. Those, however, then made the 'bar-tape appear very grubby in comparison but a little water, washing up liquid and some elbow grease worked wonders.
The last purchase, made on-line on Tuesday, before starting the reassembly of the bike was a 30ml bottle of touch-up paint and that has just arrived. A quick search on the www suggested that Porsche's (very 1970's!) 'Signal Orange' would be an excellent match and having just had a quick look it really does look exactly the right hue.
That will be a job for tomorrow.
Philip.
