The 700 series had different cockpit windows than the bigger 800 series, and had oval instead of rectangular doors.

The last two digits are specific sub-types allocated to particular airlines. Aer Lingus was 808, KLM was 814, for instance.

Quoting Rw774477 (Thread starter):

It's a shame I don't have my book Viscount, Comet & Concorde by Stewart Wilson as this book outlines it very well.

However, so does wikipedia - http://en.wikipedia.org/wiki/Vickers_Viscount

700 - the first production version, 1,381 hp (1,030 kW) engines, 287 built
700D - 1,576 hp (1,175 kW) engines
724 - 15 sold to Trans Canada Airlines (TCA) of Canada, included more electrical power, a new fuel system, and cold weather operation provisions.
745 - 40 sold to Capital Airlines of the USA
757 - 35 for Trans Canada Airlines with more powerful 1,600 hp (1,193 kW) Dart 510 engines
771D - improved 770D
800 - fuselage stretched 3 ft 10 in (1.2 m), 67 built
810 - 1,991 hp (1,485 kW) engines, 84 built

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.
