Ah, not there's a nice photo and ride, Jim; glad you were able to take it with your brother.
Your Mom's Suburban looks fine, thanks to your rehab efforts, and be on the road a good long time from now as a result. That color was called "Campus Green" and is the same color as my first Schwinn, a 1968 Sting-Ray with 3-speed Sturmey-Archer IGH and the eunuch shifter option (looked like a Hurst automotive shifter, sprouted out of the middle of the top tube, and could not be avoided on dismount -- ouch!). Still, nice memories.
As I recall, that speedo/odometer combo on the bike at left was originally sourced from Huret by Schwinn, then branded by them as "Schwinn-Approved".
I can't quite remember, Jim...are the front forks tubular, or are they flat-forged from solid steel, as on my 1970 Schwinn Varsity? If solid...Man! Those things just did not flex!
Really nice ride too, Jim, with that loop through Valley Forge National Historic Park. Good-sized hill in there, too!
Best,
Dan.
