Notes:-(1) Dates are tricky! Do you take the design date, the date "marketing" announce it (often a prototype), or the date entered service? It's all a bit vague.

"Open chassis" means the unit is rack mounting and the chassis is vertical with the valves pointing forwards.

"Console unit" means the unit fits one of the console cabinets (BD628 typical) with the curved corners and pull out slides.

"Style" means the construction is of that "Family construction style", there was, however, some style overlap.

In addition to the numbers listed above there were a great many items with just a four digit number like 4696 which turns out to be a "Cue lamp" on a desk stand.

(2) The BBC ordered 75 of the BD850 21" monochrome picture monitor for use in the new TVC at White City.
(3) Designed and manufactured by Compagnie General de as CP102 and sold under licence.
