[Buick -32 Model 80 Lincoln -27?]

Yes, only models 86 and 87 was available so it is probably a model 66.

[First garage photo]

Thank you Bill. At the time the photo was taken the Buick was not running due to a defektive cylinder head, so it was easy to deside which to drive. Now the Buick is on the road again which makes it hard to deside.
