The TCA version was the first North American version. Most of the updates requested by TCA (for certification, operational reasons) were incorporated as standard from then on.
The Capitol Airlines Viscounts were later in service with United when United took over Capitol. UA actually sent some back to Vickers, but liked them so much re-purchased them!
The Viscount is, I believe, still the most successful British airliner from the amount produced.
I do quite enjoy a spot of flying - more so when it's not in Economy!

Capitol never had Viscounts. It was Capital (as you stated earlier). Two different airlines.

United operated 47 former Capital Viscount 745D's. Compared to DC-7's, they were more than acceptable. With the addition of the Viscounts, Caravelles, and additional DC-8's and B-720-022's, UA was able to ground their entire DC-7 fleet before the introduction of the B-727 in the spring of 1964. UA retired the last Viscounts in early 1969. Other than the three DC-6B's kept to protect the SFO-RNO-ELY-EKO-SLC trip, they were the last propeller aircraft operated by United. In 1971, UA gave up the DC-6B as well, and had Frontier (FL) fly the above routing with a wet leased Convair 580, owned and operated by Frontier.
