Thanks for all the good replies fellas. This is exactly what I'm looking for, especially any thoughts on specific de-valuation.

I'm not sure how it was damaged. A friend of mine bought it on the Bay about 3-4 years ago. He was interested in one of my bikes and we struck a tentative deal to trade him my bike, a wheelset that he needs, and a stack of cash for the Masi. I then noticed that the clamps were applied at an angle and that there was some paint loss at the edges. I had figured that the clamps were applied at an angle to somehow facilitate cable flow. Turns out that the previous owner was trying to hide the damage..... What a skunk. My friend is an old friend who's as honest as the day as long, so I know that he was genuinely unaware of the dent....

I will likely still buy the bike, and will likely just neutralize the existing rust and leave as is. For a buyer like me, I'd much rather take on a bike that's had little or not restoration and live with any imperfections. The dent is really rather small, and I don't think that you could roll much out of it. I'd guess that the likely repair option is to fill and touch up the paint.

I wouldn't undertake that unless I was very confident that the shop could do a near-perfect job.... I sure wouldn't ever, ever part it out.... There's a special place in hell for anyone that would part out a stock Confente-era Masi. The gruppos are very specific to the bike (1973 RDs, Martano rims, 3ttt bars, etc.) and it would be a sin to separate any of it.

Anyone want to weigh in on hard, but hypothetical, numbers?

If, for argument's sake, a typical Carlsbad Masi is worth $2000-2500, and some cherry examples can fetch $3700 (small size in excellent condition, as a later one fetched recently on Ebay), what would something like this likely fetch? Meaning, a complete and original example in otherwise nice condition that was in a large size (probable negative) and had a dent (definite negative)?

Am I wrong in thinking that this would fall somewhere in the $1700-2000 range? Am I too optimistic? What about the long term implications? When typical Carlsbad Masis fetch 5k, how will something like this fare? 3k or 4.5 k?

Oh, I will probably ditch the clamps entirely (OA wouldn't permanently cure their ails) and replace with some NOS clamps after cleaning and coating the problem areas.

The tape will be switched to cotton and the whole frame will have a nice cleaning and wax.....
