Re: How are 28-29 and 30-31 radiators different?
Not to dwell on this too much, but the more I learn, the more I realize that I don't know enough! In comparing the viewable features of radiators on Brassworks' website, I'm not sure what it is that I have. The return neck of my radiator looks like Brassworks' 30-31, but the design on the upper tank looks like the "pyramid" beading of the 28-29, not the "vertical column" beading of the 30-31. The only thing close looks like their "transitional" model for the very end of '29. I'm more confused than ever!
