Vintage BB woes

Tried inquiring in the Vintage section, got a few hints.... Thought I'd check here.

I have a vintage Cilo/Swiss roadster, about mid-80s according to the codes on the components.
The Shimano 600 DR is toast. It seemed fine a few years ago when I replaced the crank, but working on the bike recently I found a lot of friction and inspection showed that it's done, both cups and the spindle are galled and ruined.
Thought to simply replace with a modern sealed unit but the local dealer says no-go... Non-standard stuff.
Here's the specs:
Both cups are marked 35 X P1. They are both right-threaded, they tighten to the right.
Spindle is 68 x 116. Looks like a standard taper; I've been using a Nashbar crank that went on with no problems.
Don't want to spend huge amounts of money, but this is my only roadster at the moment.

If you want a modern sealed unit, one of these should work.

Otherwise, find some french threaded cups and search for a replacement spindle (116 JIS). The second option would be less expensive but probably more hassle and time.

Your bike is French threaded (35 mm diameter, 1.0 mm thread pitch, both sides right hand threaded). The Velo Orange bb Iowegian referenced is one of the very few made in French threading and should work well. Phil Wood makes French threaded cups for their bottom brackets but they are very expensive.
