Fordson fuel tank

[John *.?-!.* cub owner]

My mother just called and she had received a phone call from a distant relative in central Arkansas looking for some information. While cleaning out a barn they came across a new fuel tank for an old Fordson. she didn't remeber what year or model the tractor had been, but did remember it had been on steel. Her husband died over 20 years ago, and I am assuming it to be NOS, but may be wrong. she thought it was a tractor from the 30s, but the lady is in her 90s, so she may have been in error about the year. She was wondering if it was worth anything, and the best way to go about selling it. So far as I know, none of her family are computer or ebay users.
