The OP did well on this bike! Watching the price go from $75 to $25 and THEN offering $20 seems a bit shameful but I may have done the same . (My B-I-L would have got it for $15 and made the seller feel good about it ). The seller must have been desperate . Perhaps the large frame was a factor for being on the market so long. That leads me to believe that the OP is more than a little bit tall. Bonus for the OP! Can’t exactly tell from the way the OP describes component swaps if the Brooks saddle was on the bike “as sold” but if so, the OP was ahead of the game from the moment of sale. Anyway, bravo on a nice refurb/resto!
