If you can get one of the early frames (threaded bottom bracket), grab it! They're real nice riders, very responsive, and putting on first line period components turns it into one hell of a nice riding bike. I got mine that way, have been putting it back to original Lambert, as much as I can. I watch the overall performance die slightly with every proper original component I add.
What's wrong with the sealed bottom bracket? I realize it is a bit interesting to service but the bearings last nearly forever, I only replaced the ones in my sons Viscount because the left side bearing had gotten moisture in it from improper storage.
His wheels still have the original sealed bearings and they still spin silky smooth.
