With Boeing announcing that they will open a 3rd production line for 737s at Renton to do a total of 42 per month, my question is, when they were producing 4 different models at Renton (707, 727, 737, 757), were they ever doing more than that total per month?

Definitely not, but the market then wasn't as large as the market now, and the four models only overlapped for a short time - a time for these purposes we'll define as the months between the 757's first flight in February, 1982 and the cessation of 727-200Adv production in September of 1984.

About 20 military 707s and about 40 727-200Advs were built during this time, not exactly numbers but not far off.

I may be slightly off but at the time the 727 line shut down, 43 757s had been completed - pretty sure that's exact.

The 737 was up to around line #850 in early 1982, and up to around #1060 in late September, 1984, so figure around 210 of those were delivered in that time (not an exact figure) including probably the first 8 to 10 737-300s.

Being generous and not particularly exact, that's around 313 planes over 32 months, or around 10 per month.

Quoting bigbird (Thread starter):

Not even close. Looking only at deliveries of Renton-built aircraft for the 3 years that all 4 types were in production simultaneously (1982, 1982, 1984...the last 727 was delivered in '84), the annual totals were as follows:

..........1982...1983...1984
707......8..........8..........8
727.....26........11.........8
737.....95........82........67
757......2.........25........18

Total...131.....126......101

Or an average of only about 10 deliveries per month of the 4 narrowbody types combined.
