A couple weeks ago I mentioned that our museum has what we believe to be exhaust stacks for a WWII Napier-Sabre 24-cylinder engine, as used in the British Hawker Typhoon airplane. Further, we think these stacks are the spares for Typhoon MN-235 (the only remaining Typhoon), which was here in Seymour, IN USA after WWII. When the airplane was rather hastily shipped back to England, some of its parts (most notably, the radiator!) were left behind. In my earlier post I said we were cleaning up one of the stacks (we have 8, total) in an effort to find any numbers or other markings. The cleaning is now complete, and we did find one number. The number 32941 is stamped just inside of the lip on the discharge end. Now that it is cleaned up, the material appears to be stainless steel.
I have attached 4 photos of the exhaust stack. Note that I got smarter for this series of pictures; I included a ruler in 3 of the views. We would like to confirm that these exhaust stacks are what we think they are. We are aware there are 2 groups working in restoring a Typhoon to flying condition. One is in England, the other in British Columbia, Canada. Since these parts are stainless steel, they did not deteriorate badly during the period they were buried here in Seymour after the war. Our stacks may well be airworthy parts.
Thanks for your help.
