The Tiano radials are meant for warbirds with cowled engines. They are cast resin replicas of the FRONT half of a radial engine--just the part you'd see by looking into the front of the cowl.

Not useful for a fully exposed replica radial, really. Williams Brothers is the only solution, other than scratchbuilding one. FWIW, Williams Brothers Model Products is back in (limited) production, as of this month. Fortunately, I have a little stash of NOS WB cylinders already squirreled away that I'm going to be making my GP PT-17 engine from. Agreed, the supplied one does look pretty dumb. It's a shame they didn't take the time to make it look right. I don't know why this is such a difficult thing to replicate.

Great news for those of us who need replica engine cylinders, WWI accessories, pilot figures and the like.

Incidentally, the PT-17 is a calculated 1:5.33 scale. That's kind of dumb too, isn't it?
