Howdy, We’ve been using our raised flue 3 by 10 arch for 28years now. The rectangular (ish) cast base casting has rusted and rotted through in a couple of places and cracked through to center hole on the pan side. In short it needs replacing. I am hoping someone might have a good used one out there I could purchase, or might be able to point me to where I could get one. We are going to be retinning and rebuilding the arch after the 2021 sugaring season and this is one part I am lacking at present. I may have to replace the front castings as well. Please Advise.Thank You. Tomm of Hermitage Maple.
