I wonder if it wasn't so much the size, but the air valve associated with the two sizes - presta for 700 & schrader for 27. In 1982 that was my concern. The lack of accommodation for presta led me to recommend schrader for those in my tour group. I think at that time it was still unclear which valve was going to be dominant in this country.

Even though they were certainly fading in popularity, 27" wheels were certainly not obsolete in the early 80's. Trek's 1983 high-end touring frame/bike (it was available both ways) model 720 was built for 27" wheels. The explanation I remember hearing was that Trek still believed that a "touring" cyclist would have better luck finding 27" rims and tires in remote areas, as opposed to 700c. I'm not really sure if either that perception or the reality was the case at that time though.
I also want to express my sincere best wishes to everyone for a great Holiday season and a fun, happy and safe New Year.
Cheers!
