I was doing a lot of research on mid-war Elco PT's and came across this photo:

Note the unique radar mast.
I can't find anything about this particular boat. The only information I can find is on boats with either the non-radar, mid-war cylindrical, or late war rotating radar masts. The one pictured appears to be unique as I said. I for one think it looks the coolest of the bunch and as a model would probably be the most distinctive and durable.
However this is the only image I can find of it. Does anyone know anything more about it? thanks.
money can't buy happiness but it can buy an RC boat which is kind of the same thing. |

This photograph is sometimes captioned as PT 149 but I have not been able to confirm this. She carries the SCR 517 radar set. It was an aircraft set, S-band, used in the P-61 Black Widow. A number of boats from RONs 7, 8, 9 and 10 used them in late 1942 and early 1943. The installation was an important first step but the device was not well suited for PT use. In 1943, Raytheon developed the SO-A set specifically for use on the boats which included the PPI scope.
Hope this helps,
ALEX

It does very well. Its a pitty it wasnt a success because it looks great. Do you know where I could find other pix of the same design?

spacephrawgg,
I've always thought those SCR-517A PT radars were interesting, too, and I've mentioned them a few time on the messsage board -- not that I know that much about them. They were nicknamed "beehive" radars because they looked like one, due to the appearance of the ribbed frames underneath the cloth covers.
Besides some earlier, jury-rigged and unsuccessful radar setups with foredeck-mounted antennas and charthouse-mounted wires, they seemed to be the first PT radars that were purpose-built (albeit adapted from P-61 aircraft sets, as Alex mentioned) and worked (sometimes).
Check out the book "United States PT - Boats of World War II In Action" by Frank D. Johnson. You'll find several other photos of 80' Elco PTs with the beehive radars in it.
