Hello all

I recently purchased a Honda motorcycle fuel tank for a CT110 project I have going on, I was told it came from an older CB 200 but I don't think that's the case and I've spent almost the last 3 weeks trying to find out what bike it came from so I can get a fuel tap for it. It's the last piece to my CT project build and it's driving me insane.
I even went to a local Honda dealership and they had no idea either.

Please help.
