Those pictures (and logo) are identical to the one I had in mind that I've seen before... as you say, no internal wire forestay.
Here's a link -http://rigrite.com/furling/stearn/stearn.html
EDIT: the link isn't pasting in clean - but that's the correct URL - I think the product highlighting on "Furling" is messing things up.
I think it's a Stearns Twin-Stay ONE, probably the first twin groove foil produced. Check the link, there's a cross sectional drawing and description a little ways down the page. The site says that parts are still available.
However with its forward facing groove that's a difficult foil to use compared to newer versions. I'd replace your forestay with wire and get a Tuff Luff or similar foil to install over it. This would be a far more conventional setup today.
Shipping such a long piece (unlike new foils which either roll up or come in sections) would add significantly to the cost.
