Hello,
Ok, so the nomenclature is a bit more clear to me and now that I look at the barn here where I'm living, which is typical, I see that the reverse assembly is the standard way these barns are put together and normal assembly would be a deviation, at least in Holland. I always knew these folk were a bit skewed. Anyway that's clear now and I didn't mean to steer things off course by any means other than to say, it does suggest, as Ken Hume writes, that reverse assembly could have origins in Europe.

Greetings,

Don Wagstaff
