Nice bike! Good way to memorialize someone who was close.
Have a similar Maillard freewheel on my Moto Super Sprint. I'll get around to a tooth count on it next time the wheel is off. The stacked looking construction of it had me first thinking it was an early cassette. (It does share the remove-able cog system a bit with the later cassettes)
I know a couple of rides isn't really enough to form an opinion on the tires, but what do you think?
Don't see gum/tan-wall Conti's around here very much.
