Several
Falcon bicycles, from the early to mid seventies, have come my way over the years. I believe this one is close to identical to yours...
I would recommended that you change the wheel rims to alloy. If you do so the ride and braking quality will be noticeably improved. Also...
Though the bicycle looks to be in great shape, the grease in the bottom bracket, head set and wheel hubs is, likely, shot. Time and environmental concerns, tends to destroy the lubricating quality of grease.
Other than that, for now, enjoy the bicycle.
