Current Projects chat and miscellany

Alright, I'm almost done with my build, but I need help to pick out the last few components.

Parts:

Frame: Eddy Merckx with Columbus SL tubing. Need help dating the frame.
Forks: Supposedly the original ones that came with the frame. Can someone tell?
Campagnolo Pista bottom bracket
Cranks: Campagnolo Super Record Pista
Hubs: Campagnolo Record Pista
Rims: Mavic MA40
Headset Campagnolo
Seatpost: Campagnolo
Saddle (current): Selle San Marco Millennium
Bars: 3TTT
Stem: 3TTT

I need pedals, cages, straps and a saddle, but.. What would you do?!

Also, I need some kind of braking device.. I'm not too keen of drilling the fork and mount a brake, so I'm down to two options:

A: Buy a Dia Compe clamp-on brake in silver. I am not too sure whether this is going to ruin the looks, as it tends to look quite massive.
B: Buy new chromed forks pre-drilled, and install a brake.

Both leaves me to the question: Which lever, cable and brake would fit my build?

hi kvik, some info here on Columbus tubesets

the track forks whether original EM or not are too nice to drill; very often they would be pantographed/stamped EM on the crown. Suggest a set of chrome straight forks for the road, such as BLB's offerings

If you want the bike to be early 80s flavour then record or super record parts; if later then you move into corsa record, if staying campagnolo. if you want effective modern stopping then bung on a tektro dual caliper, or spend up on 105, and get some white hoods

kingcutter's advice probably best, keep it for the track and put together a road machine
