WW2 BMW ?

I've finally had phone contact with the landowner who claims to have a WW2 BMW sidecar rig.
The gentileman contacted me through a Craigslist "wanted" ad.

The currant owner purchased a large section of property which the old owner had spent years filling full of junk. The new owner has spent the past year or so clearing all the junk out.
An old semi trailer there held a bunch of old Harley Davidson parts / bikes which the guy sold.
Also in the trailer was this (supposedly) old WW2 BMW motorcycle and sidecar.
It is possible the bike could be an old Russian bike or possibly an old Chinese bike but you never know. The owner had a friend do a little research but never did pin down exactly what it is.
We have made arrangements to meet the land owner there next Tuesday to look things over.
The sidecar is separated from the bike and hopefully things aren't scattered too far and wide.

These kind of finds don't come along but once in a life time, if it is in fact, a WW2 Military sidecar rig. I'll definately take my camera but not the trailer on this trip.
The place is only about 2.5 hours from my house so I can always make a trip over with a proper trailer if the bike is a legitimate military bike and if we can come to a price agreement....a lot of "IFS"....
I'll update the story as things develope.
