I need your help to identify this Viscount

Airco, welome to the forum - that is a very nice high quality Viscount Aerospace Pro. Dating is best done from the Shimano components which have letter/number stamps which are sometimes hard to find but will be on there. Check down the bottom of this web site (ignore that it says Trek at the top, it does have date stamps for Shimano components )
www.vintage-trek.com/component_dates.htm
It could be anywhere between about '75-'78 I would guess.
And looks to be all original except maybe saddle? So, dating should be easy with the Shimano parts.
Very nice indeed and welcome to the club! What is the story behind your purchase?

By the way - You perhaps need to read up on the fork, and make a decision based on all the facts, before I bring up the words D*&th F*rk and put you off.

Welcome to the wonderful world of Viscount bicycles! That's a good find, and looks almost completely original except for the saddle and pedals.

My Aerospace Grand Sport came with the same chainset as you have (see below), so yours may well be an original fitment. I think it looks very elegant. They probably ran out of Porthole chain sets on the day they made yours, so they put the other one on - not unknown among the Viscount assemblers, apparently.

The crankset is a copy of the TA Cyclotourist crankset, with the 5-hole boss (about 50mm BDC) at the base of the crank, then six-arm chainrings just to confuse you when reassembling them. Apart from the characteristic looks, the advantage of the Porthole chainring is that you can convert it to a triple using the smaller (80mm) BCD of the inner circle of chainring bolts:

If you do look for a replacement fork, check the diameter of the fork crown race seat at the base of the steerer tube. Some readily-available 1" steerer CroMo replacement forks have a 27.0mm 'JIS' fork crown seat, which means your original headset's crown race (possibly 26.4mm 'ISO') might not fit unless you have access to a machine shop to either turn the steerer tube seat down or open out the crown race. Good quality headsets with 27.0mm ISO crown races can be hard to track down. (Dare I suggest a Carbon Fibre replacement fork? The purists among us would be aghast!)

P.S. Take good care of those perished-looking white/cream rubber covers on your brake lever hoods - they are objects of desire around here!

Thank you guys for your answers ! Firstly sorry for my English (I'm Belgian and i speak French ).

I've bought this bike for 80€ (+- 63 ‎£) and i would like to restore it. Thanks to your help i think that i can say that all pieces are original except the saddle. I've dismantle the bike and almost all pieces are ok except the brake cables. I will all clean and polish up !

I'm hesitating about the new painting... I would like change the original colors, keep the blue which is very nice and flashy but change the grey into an off white. Do you think that it will stay respectful of the authentic bike ?

I'm a rooky in this domain so if you have some piece of advice, i am all ears !

P.S. : I did some research about the famous Death fork and I think that is the second version of the fork so not the most safe but not the most dangerous... Just acceptable i hope

Your English puts my French to shame, so don't be sorry about it!

Hi

How is the resto going?

Steve

airco-

Looks good! One small suggestion - the crank arm should have the outside chain ring mounted in front not behind as you have it currently. It is better supported that way. Check the 2 photos in robt's post to see what I mean.

I agree with bicyclebits that the chainring will have better support when on the outside of what these days is the 'spider', and it will also give a cleaner (smoother) look when seen from the drive side of the bike, as in the pictures of Rob's.

The bike has cleaned up very well and looks good, and I like the red top with saddle and handlebar tape.

Red, white and blue are the colours for Britain and France - are they also the colours for your part of Belguim?

Aha, airco, don't worry about where the red is!

I don't see colours properly as my eyes are not very good at seeing green, and that affects how I see other colours. In English we call it being 'colour blind', we do see colours, but we don't always know what colour something is, and we often get colours mixed up!

Take no notice of what I said about the saddle and bar tape.

I do say the bike looks good!
