I have 707-320Cs, -420s, and 720s that I am looking to trade for DC8s.
I am looking especially for DC-8-55, -62, and -63 variants but also willing to consider
If anyone is looking to add to your 707 fleet and get rid of DC8s, I would be happy to do an equal exchange you (sell at calculated values, so I may pay more for the DC8s; just without an additional markup on top of the calculated value of either my planes or your planes).
My 707s are in good condition, and you can take your pick of the youngest planes, or the ones with most recent heavy checks, etc. The best ones are not yet posted to the market, so please contact me for a private listing if interested.
