- Are pictures available (on the net) of the actual modification in the Boeing factory in Seattle. I can remember that some were publicized in KLM magazines.

Thank you for searching on the Internet for me
However all these STC's are from the (inside) extension of the upper-deck to put pax. seats in the former lounge area. During this modification also extra pax. windows and one extra emergency escape door was added on the left side. Most 747-100's and early 747-200's were delivered with one RH emergency escape door and 3 windows at each side. All above mentioned STC's were performed around 1980.
KLM performed this modification on 747-206B aircraft, powered by JT9D-7W engines.
These aircraft did not receive the upper-deck extension to make them 747-300's look-alikes.

If I remember correctly, I thought I read that the first or first couple of aircraft where modified in Everett and KLM did the rest in-house.
|Quoting DH106 (Reply 7):|
PH-BUF clearly wasn't around at the time of these mods.
|Quoting 747classic (Reply 6):|
All aircraft were modified in Everett.
