juvela -- my communications with the seller were limited. He offered me the complete bike, or just the frame/forks, with the BB & headset. I opted for the latter, since I couldn't have used any of the bits it would've come with (all of my bikes are set-up with porteur bars on a tall stem, geared hub w/ backpedal brake, front drum brake w/ inverted front brake lever, 177.5 or 180mm crank arms, etc.), so paying twice as much for shipping, just to receive parts I couldn't use, was pointless. And from what I recall, his components were nothing special.
But now that you mention it, I can see why the front derailleur location might be a challenge. There's no braze-on for it on my frame, so it must've been a clamp-on.
Sorry I can't be of any help with your question.
