Can't find any Crawfords with a similar-sized head tube.

There were others in my family living in Hagerstown...hmmm.

He might have used the Crawford sprocket to fabricate the disc brake, so this could be useful.

Thank you. That looks pretty similar. But the 5 spoke disc on the left is the brake, not the sprocket. The chain sprocket is still on the right. Also, the head tube seems too long.

I was incorrect about county paving out to Walnut Grove during anything close to that time frame. "On the 23rd day of July, 1913, the County Court received a petition signed by many property owners in that direction praying the court "to pave with brick or concrete to the Glaze property;"...

Is this flange an identifying characteristic? I edited out the tear in the image that was near this flange this morning. The flange may have been on both sides of the fork but it is difficult to say because the tear was there.

If you are a descendant/relation of any Glaze, Butcher, Douglas, or Rogers from that area, I can add you to my genealogy research/photo restoration group.

Maybe Pierce Special Model 44? I found a marketing image and flipped it and then placed them side by side. I can overlay them when I get home to my computer.

This is the Walnut Grove near Spencer in Roane County. It's pretty much a ghost town now. But the terrain is pretty hilly. They paved "out to the Glaze land" at some point but I can't remember the year.

I am wondering who made the bicycle, not who made the attachment.

I recently found a patent filed by my great grandfather in 1899 for a bicycle brake. Some months later I was restoring an old photo of his family and realized that the brake he designed is actually on the bicycle that he is proudly standing near in the photo. I am trying to identify the make...
