Models prior to the G or H (1956, 57) IIRC. The J, K, M ('58 - 60)
were 140 mph and the newer ones crept up to 157 or so.
(mph or kts??)

Were they even fast enough to require flaps? :~)

They were about as fast and slippery as today's models. That made
them a real challenge. :-)) On mine (59 Debonair) the full flap
speed is 120 while gear down is 140.

They were definitely about as slippery, but I don't think they were "quite"
as fast. :~)

By the mid to late 50s they were into the upper 170 knot range. With
the exception of the TC models at altitude speeds, have not varied
over a couple of knots since.

The very first Bos only had a cruse in 150 knot range. (1947 into the
early 50s) It didn't take much additional HP to put the speed right up
there, particularly with the lighter weight models.
