General: '69 Crescent - what's it worth?

I am new to road bikes. I put an ad up on craigslist to sell my cruiser (a '41 Columbia Replica) so i could use the $ to buy a road bike instead because I've started riding alot more this year. I got a bite back from a guy with a '69 Crescent who wants to trade. I've had a really difficult time finding out what these bikes are worth from researching on the web. I'm selling my Cruiser for $350 which is an Awesome price already. I figured i'd tell the guy i'd take the Crescent + some cash as trade for my bike but i have no idea what the Crescent might be worth. He sent me pix of it. It's the standard orange w/ decals. Does anyone know roughly what one might pay for one these days?

my friend picked one up and converted to fixed since all the ten speed components were trash. I saw one tonight in good condition still as a ten speed.
The Crescent is Swedish made and there are only a few different models.
Price would depend on the condition of the parts.
$300-350 sounds good, again depending on the condition of the bike/parts.
Again really awesome rare frame I'd get it.

My buddy has one right here on velospace, send him a note. I think his has campy components.... http://velospace.org/node/19315
