I've always like the looks of honeycomb radiators. I have one for my Mercury project, but it needs to be re-cored. I'm looking for the experience and advice of those who have done this.

A good place to start would be to find out if a new core is available. BTW: I like the honeycomb look too.

Is anybody who knew how still alive? It wouldn't surprise me if you had to get a "correct" radiator recored. But I'm just guessing. I've been wrong before, at least once.

I have bought some honeycomb core material from a supplier in New Zealand. Probably 20 years ago now

Replicore is the name of the company in NZ. They have an ad in the HCCA Gazette Magazine.

Yeah, I can google. I've seen the place in New Zealand and Maine Radiator. Maine Radiator gets their cores from the UK and does not re-core. Has anyone had one re-cored and what was your experience?

I went a completely different route with very nice results, rare radiator made new, but still looking old and rare.
The custom bodied T acquired had a special square honeycomb type, that could not be replicated, and even other sources noted, couldn't provide a quote, just saying time, material availability, and transportation costs.
So ended up with Universal Carnegie.

That special radiator core leaked, and note the inside view of the square pocket core, rather difficult to replicate.

The fix by Universal was to replace the core with their own mfg. 'heater core', which functions as a radiator just fine, and my results with the radiator were great, super cooling. BUT...the main thing they did was to SAVE the face of the original core, by cutting off 1/4" or so thickness of the original square core and soldering it over the new core, so from the outside, was the 'original'. Very good result IMO.
Here is the new/old look:
