"Both the Silver Ghost, second from top of the line and the Mistral, third, had near identical frame set. Both were Reynolds 591 straight gauge tubes. "

The frame sticker clearly says Reynolds 531 frame tubing. Those prices on your web page must be not be in US currency. My Silver Ghost was tagged at the dealer at $225 in 1973. He took a few bucks off due to misinforming me about having a Mistral in stock. I will always remember that trip because the dealer had a penny-farthing replica in the store and he let me ride it. Man, was that a weird ride.
