But it's the little details which make or break a restoration, and as the 'bars are one of the focal points of the bike then the levers need to be "right". If the blades and perches were clearly a mismatch it would pee me off every time I rode it...
I understand that, and if I were to do a resto, I'd be same if not more anal....but as far as I can tell, the lever combos you have are not listed for yours in the spares list anyway, so as I said- must be an 'Original retro-fit' (as opposed to a later retro-fit- like now)
All that is why I chose to never intend to restore, but to rebuild to suit me.
