I have a SWBO project ready to go, if demands can wait. Otherwise I have ideas for an ORBO bike… Urban Assault. As always, TBD. Post-Turkey I’ll escape to the garage to ponder inventory over a good beverage.

Actually, they're both Shelbys. But I have to assume you mean the late '30s wishbone double bar with the Shock-eze forks and great original paint

This is a Western Flyer badged frame that I bought from JAF/CO during Covid and just haven't gotten around to building yet. It's one of my bucket list builds and one of my favorite frames. The plan is to build a klunker using vintage Sturmey Archer drum hubs with a 3 speed from a tandem that I bought around the same time frame. That's been the hold up for me. The rear hub is a 40 hole and front is a 32. I finally have the rims, aluminum 26" MTB rims, so it's ready.

The other one is, I think, a '53. Also a wishbone though it has been repaired and the wishbone area around the seat tube is pretty full of braze

My plan for this one is to use a vintage beehive springer and mostly mountain bike parts. 26" wheels, 3x7, etc. Bare metal with the brazing highlighted. Either way, I'm having fun!

you’ll be fine with that concept, using a rear derailleur. For a single speed, the curved chain stays make for chain drag on the chain stays with almost all non original cogs and chainrings. Some, but not all of them, have a low ground clearance making for pedal strikes and headers. I built a klunker with a frame similar to this one with the curved stays and had to use 5.5 inch cranks, which made for real choppy peddling. I think most of them have enough clearance for a 6.5 inch cranks. I ended out giving the frame away.

This drawing is over five years old and has been through hundreds of revisions. I really think I got the design pinned down now though. My goal is to eliminate all the stumbling blocks I've hit in the past. I was always hung up on making it perfect but now I'm just taking more of a prototype approach for this build. In certain circles a "dutchman" is a nickname for a repair in a woodworking project. Hence the name the flying dutchman. I did google it though and it turns out it's a famous ghost ship which I thought was pretty cool.
