Dear Phil,

That Slingerland model I think is very similar to a short-scale Lyon & Healy I recently sold (probably made in the same factory in Chicago). My Lyon and Healy fetched € 520 (+/- $ 670 or £ 356). If it is a 17 fret short-scale they are fairly sought after by Irish players and somewhat harder to find than regular tenor banjos (19 fret) (particularly in Europe so value may be a tad lower in the States if you are there)..

Hope this may be of some use.

Peace
