Murphy, I have a bunch of old clunkerish shotguns.
Your descriptions are too vague to be of much us as far as a valuation.
Start by taking the barrels off, and look for Belgian proofs. If it's a T Barker Belgian made clunker, then it's not worth more than $150.00 to me. Great condition, and tight (without forend on it) maybe 200.
They need hand loads or low pressure commercial ammunition at $12.00/bx. for starters.
They were $25.00 guns a hundred years ago.
But, if you came across a high grade, well covered with engraving, premium shotgun, then it's worth additional research.
I turned down a Remington 1894 ejector shotgun for 150.00 last week. Sketchy barrels, and a stock that had numerous cracks and repairs. So, look carefully at that Barker.
Start with removing the barrels, and looking at the proof marks.
If you are uncertain, take a phone pic and post it. Rub some chalk or shaving cream into the stamps if they are hard to see.
