It's not retro, so apologies if that's what you're after. I would suggest a Thomson X4, if I wasn't looking for a period item. It's available in 120mm.
Available from many places. It's technically a mountain bike stem but no reason you can't use it on a road bike.
The road version (X2) also comes in silver, but not a 0 degree rise.
There are a number on eBay right now - none of them mine.
Cheers,
Steve
