At some point previously the tank has been rubbed down and filled ready for painting. Profile is smooth, it has no filler inside - and it is rust free / solid.
All the seams look good (no holes or splits) but note,
I HAVE NOT TESTED / HAD ANY PETROL IN THIS TANK. This is a heavy solid item. Note - no tank cap, or tank badges, although the 6 x holes are there ready for the 3 x screws for each side badge and threads are ok.
Any questions, please ask me. I am in Hazlemere (Bucks) so you can come and collect for free if local, else I will package it up nicely and arrange a courier to deliver it - price c.£15.00.
Thanks for looking - John.
