'51 Zenith Porthole

[John Marinello]

Hey Charlie, Those insulators pop up now & then, so I wouldn't try to sub it with anything else just yet. I've seen many many porthole Zeniths, and only 2 have had brittle insulators. The sets have been in barns, attics, basements, you name it. So, I don't know what causes it. Maybe the supplier goofed and had a bad lot? I do have a cracked insulator that you can have, but wouldn't be worth shipping it. But, I could bust some pieces off of it and maybe you could cut some puzzle pieces to make it look better for now?
