Ah. Neat. I wonder what the price of the earliest Campagnolo version that would fit might cost…
…no, not going to look. I think I don’t want to know.
They’re even more than that for some on eb*y12 pennies each in 1950, so 24 pence a pair. £7.50 was the average weekly wage in 1950 for a laboring man. Considering £1.00 back then would have the buying power of nearly £44.00 today, those downtube stops cost the equivalent of £11 today.
