With 2 engines and the intakes above the wings/fuselage, it reminds me more of the seaplane fighter Convair F2Y Sea Dart.

Model of Convair F-102 Delta Dagger concept marked "CONFIDENTIAL" on base found on eBay. Model is made of wood. Thoughts? Real?

Every factory YF-102 model I've seen shows the boundary layer separators at the intakes. These also appear on the MX-1554 pre-design models that preceded the YF-102, and even on the small, plastic desk models. Their purpose and configuration were well-established by then. Every Convair document from that period shows how the boundary layer air was ducted to the refrigeration intercooler. Based on the inaccurate and questionable intakes shown here, I have to wonder about this model. It's definitely vintage, but I think it was made by a hobbyist, not by Convair. If someone knows more, please do come forward ...

Those I have at home are a mix of wood and fiberglass. They are also about 35% larger than this one -- which is another issue: all the Convair delta factory models I've seen are at the same scale, but not this one, oddball model. However, another SPF member thinks it's authentic ...

I have my doubts about the "XF-102" designation... Not kosher I'd say. Thoughts, anyone?

I believe, at first, the '102 might have been known as the XF-102 but since the XF-92A proved the eXperimental part of the delta winged program the '102 was given the prototype designation YF-102 instead. Just my gut feeling. -SP

Historically, I believe that the distinction between X, Y and No prefix was the level of fabrication tooling that the goverment would pay for to be used in the construction of the airframe. An XF airplane was hand-built, a YF airplane was built using soft tooling and an F airplane was built on a series production line. By this logic, the first example of an "ordered straight off the drawing board" aircraft like the B-26 would be designated B-26. It was only indirectly tied to the level of confidence in the design. The complexity of modern airplanes limits the ability to build without tooling and the amount of hardware evolution possible after the first example is built so we see fewer X and Y planes.
