Holdsworth restoration: stage one

I purchased a shabby but interesting looking bike from an ebayer in Lancashire last week with the intention of restoring it slowly to an operable and attractive state for L'Eroica classic sportif 2008. My first task is to tie down exactly what it is and what it should look like.

It is certainly a Holdsworth and I am pretty sure it is a fairly early one but the exact year and model alludes me. Here is what I know...

• The frame number is 6497
• It has a bronze 'prancing horse' badge on the head tube - just bronze with no enamelling
• There are no 'spear'or pierced lugs but it does have moderately 'fancy' lugs on most of the joints (including those around the bottom bracket). These are mostly in the form of two lobes and central point.
• The frame is painted a dark green with no sign of transfers
• There is a grease nipple for the bottom bracket
• It has a very old (original I suspect) Brooks Champion B17 Narrow saddle. This is stamped

• The stem is a forged 'GB' (standing for Gerry Burgess not Great Britain)
• The bell featured in the pictures is a "Ricspur" (patent number 607049). This was probably made at the Ricspur works in Walsall.
• The pedals are Brampton B8s (produced by Brampton Fittings Ltd., Downing Street, Handsworth, Birmingham) of a currently unknown vintage
• The chainset looks like a Williams from 1957 (thanks to Clive Holmes-Dowkes for the tip). It bears the mark

I suspect this is a red herring (as these items might be later) but it has a Campagnolo Gran Sport rear mech (with a 4 speed cassette), a campag front mech, Normandy hubs and MAFAC centre-pull brakes. Thelevers are stamped MAFAC and the straps are marked Breveté SGDG (Sans garantie du Gouvernement)

I've added some pre-cleaning pictures below.
