i have a 4x4 V flue pan. the pan is made of tin (duct work tin) i acquired it when i bought my syrup pan. it is in good shape other than for the light rust on top if the flues. it does have a couple to mate up to a 4x whatever syrup pan. i am willing to trade the pan for a 4x5 syrup pan that has a flat bottom. (no ripples) i am planning to cut holes in the syrup pan and drop flues into the holes. let me know what yopu have or if you want to make an offer. im open to negotiations. my number is 330-281-8728.call/text, i can send pics via text
