Actually, what I meant to convey is that my stable of older bikes (from various Canadian, UK, and Japanese builders) centres around the mid-80s! Not one a Davidson, unfortunately.
A couple of my favourites are built date to 1984-5 (my Mercian Pro, for example); my feeling is that many craftsmen and larger manufacturers hit a sweet spot around this time, producing wonderfully clean, elegant road frames.
Which probably makes my last comment a little clearer (I literally picked up my first US-made bike from the PO 15 mins ago!)
Really, really dig your Davidson!
