1960s Falcon Track Bike - The British Italian Job

@anidel helped me find some information on the frame and he posted some catalogue pictures in the sales thread which identified the frame as a Falcon San Remo Track. The San Remo was the top of the line model and used Double Butted Reynolds 531 tubes all around. This particular model, unlike the san remo shown in the catalogue, has Nervex Pro lugs.
Here's anidel's post from the classifieds thread:

These are the framesets built around 1970s, if this is true and no other types of track frameset were made (but surely they had made some on order), then this should be a nice 531 quality frameset:

Here are the models from the 1970's in ascending order of quality:

Model 58, 68, 64: Junior Racer, smaller frames and wheels
Model 70, 71: Black Diamond, seamed tubes
Model 74: E.C., seamed tubes
Model 82: Super Tourist, seamed tubes
Model 88, 89: Super Tourist Deluxe, Reynolds 531 plain gauge seamless
Model 80: San Remo Cote d'Azure, Reynolds 531 plain gauge seamless
Model 78: Olympic, Reynolds 531 plain gauge seamless
Model 92: Super Route, Reynolds 531 plain gauge seamless
Model 90, 94: San Remo, Reynolds 531 double butted
Model 96, 98: San Remo, Track Bike, Reynolds 531 double butted
Model 76: San Remo, (aka Equipe or Professional) Campagnolo NR, Reynolds 531 double butted

Also 1970s catalogues shows this was indeed the only track model (but called Model 98) and it was in 531: velobase.com/Resource_Tools/D­ownloadFile.aspx?Path=%2fCatalogScans%2f­Falcon.zip&FileName=Falcon.zip

but it doesnt' look the same. Also the headtube lugs look kinda fancy and more Nervex than Prugnat.

So I researched some more about Falcons with Nervex lugs and found this:

Another San Remo Road Version with Nervex lugs, the owner which is quite a bike nerd himself (has over 50 bikes) dates this bike somewhere around mid to late 60s. So I think that mine is probably from the same here late 60s early 70s.
