1989 Okanagan to Airstream History Question

[Oldbagpipe]

I am trying to locate some history, with respect to the few 1989 B-190 prototypes made by Okanagan, prior to the transfer to Airstream. What I understand is that in the first year (1989) the Airstream B-190s were constructed in British Columbia by Okanagan. After the first year, they were then transferred to Jackson Center, OH.

Mine has a build-date of June 1988 with all the Airstream badges and decor, but an Okanagan serial number. I would love to find the sequential number of my unit.

Any help or direction is appreciated.
