I'd like to get the bike going again in memory of my beloved brother-in-law, who owned it for 50 years. The frame issues must have been what caused him to quit riding it around 1976. My guess is, the hole in the lower left down tube might have been caused by striking something; and an attempt to patch it failed, with only a big lump of weld material remaining. Also note the two tabs I've circled. Looking at the photo, the one on the right is hard to see because it is been over; but both are welded on, and both have a semi-circular profile. Just below the one on the left you can see where another tab was welded and subsequently broke off, leaving a small rectangular-shaped hole. I'm thinking someone fit a center stand at one time, and this is all that is left. But I also noticed there doesn't appear to be a lug for a side stand anywhere, and I see plenty of photos of P11s with side stands. How do they attach? I'd appreciate a photo if you have one. And of course, any leads on getting my frame repaired are welcome. Are there sources for tubing with properties similar to 531? Anybody out there have a bad P11 frame with a good left downtube? Thanks!
