I have a linhof Aero-Technika 45EL for sale..It has a 150mm Symmar S lens in a helical focussing quick change mount. The set includes 5 4x5 double film holders, a 6x7 roll film back, an infrared filter, a yellow filter and a spare ground glass back..
The whole system is in incredibly good condition..it doesn't really seem to have had much use.. As a studio based photographer I've never used this and i'm not sure when I bought it that was the point! It is such a fantastic thing to have , I have just downsized my studio and run out of storage space ,i'm also having to come to the realization that I'm never going to hang out of a helicopter with this beautifully made piece of Linhof history.

This is from the indispensible 'Linhof Camera story'..

The Electric Motorised Aero 45EL for Oblique 4x5in.aerial shots featured prominently in American and later in European space missions. The Camera yields highly detailed oblique aerial views from space.It has a motorised vacuum film magazine holding 5in.wide rollfilm for 150 exposures. Vacuum cycling keeps the film absolutely flatduring each exposure. The camera can also use other film holders. Helically focusing lenses, in quick change mounts, are available in focal lengths 90 to 250mm. They are also suitable for air-to-air shots and for groundrecording applications. The 45 EL is powered by either by a rechargeable battery or from the aircrafts inboard power supply.

This camera came without the vacuum film magazine.I've seen them up for sale every now and then, if this camera is to be used then it is totally viable to use with 4x5 cut sheet film.
Any questions that you think I might be able to answer feel free to ask.
I will send this via UPS in the states and however might be economically viable and agreeable to the buyer internationally. 
Thanks.
