I own the 1933 model shown on the CR photo link. I purchased it a few years ago from Steve Maasland and it is a beauty. It features the Vittoria Margerita shifting system and has a very unique chain oiler spiket on the seat tube just about the chain. Nice integrated headset and all around a neat bicycle. There are some distinctions on the lugging you may infer but nothing really stands out singularly like other brands. Still a pretty unique item in my collection.
