Juvela,
The main tubes are Reynolds 531 straight gauge tubing. I got it all painted, looks nice. Then other projects came up. I'm short a few parts to make it a complete bike.
Then a couple weeks ago I picked up another Hosteller, in my size. I have it all repainted. Just have to build it up. This one is a 70's model with Mafac Cantilever brakes and triple chainrings. I'll take pics of both tomorrow and post them here.
