It will probably be hard to find a decently straight tank for a motor which has been in service for 80 plus years so you might have to break out the Bondo and elbow grease and settle for a painted one instead of polished. At least one member here has taken the time and effort to straighten and polish dented tanks and the finished results are incredible!
I do have a fairly decent KD-15 tank here but need it for a future project. Sorry. Here’s a 9.8 horse KA-37 tank which had lots of wounds on it so I ended up painting it with automotive base/clear.
