Anyone heard of a company called Velo Orange? Do have a look at their website because they make products that are of great use for Viscount fans. http://velo-orange.com/
First, they do a threadless bottom bracket for stripped shells. The really good thing about this one - apart from the good build quality and reasonable price - is that you do not need to chamfer or face the shell (unlike the Mavic or JST ones) so you could revert back to the OEM sealed bearing method if you wanted to. You would still need to ream out the seat and down tubes where they protrude into the BB shell. Velo Orange do the threadless BB with the all important 122mm spindle length so no problems with the OEM chainline. Just checked stock availability - the 122mm is out of stock.

The distinctive 52 tooth 'porthole' chainring that was fitted to the 1970's Aerospace Pro, GP and GPM (strictly USA only for this model) is tough and long lived. This was not always the case for the TA copy cranks though which do not always take kindly to being removed/refitted. Again Velo Orange can help out here as they make 50.4mm BCD cranks which fit the distinctive chainring (and the 42 toother that goes with it)and old TA chainrings which are still out there but getting harder to find. Quality of the Velo Orange cranks is superb. They are even mirror polished too (nothing wrong with a bit of bling is there?) and in my opinion the price is a bargain. The only potential fly in the ointment is that the cranks have a JIS taper. IF your Viscount BB spindle has 2 circlip grooves only then you will have no problems. That spindle has a JIS taper
. If you have an earlier 3 circlip groove Viscount BB spindle then you have a bit more of a challenge. The taper on this spindle is unique to Viscount
. You can persuade the Velo Orange crank to fit it but you will struggle to get it to sit square on the spindle and risk damaging the crank's tapers (err, I've done that in the past with Shimano 600 cranks). To be on the safeside either use a JIS taper Klein or Phil Wood 125mm spindle with 6003 sealed bearings or Velo Orange's BB referred to above.
