So I've been reading these forums for a while and finally decided it was time to join. I've been desperately seeking information on this arrow 2200-a insert from the 80s. Particularly firebrick vs cast iron liner. I believe it came with cast iron but I have seen conflicting information. Any help would be appreciated.
