FWIW, I went through this about a year ago...I looked high and low for the 34ICH with the "27" on the barrel. I called every Weber distributor I could find in the US, each one told me I was crazy and that they didn't know what I was talking about. I asked Mark Ashcraft what the 34ICH carbs that he sells had stamped on them and he said "29," and that it was more an issue of getting the jets right. I followed his jetting specs and the carb is set up and running fine. I made sure that everything else was set up properly first - valves, new plugs, timing.
It still is running well and it fires right up. The only issue I had was to tweak the idle after a few months; it had dropped to about 500 rpm, but it never stalled. After that I've not needed to play with it.
I don't know what to make of the 27/29 debate. The 27 is the holy grail, maybe? I never found it. If you do manage to find one, please report back. Thx...
