For those building Italeri's new 109 kit, Dave noted that the port plate was cut short. I added some perspective views for clarity and moved the armor from the bridge / chart house page to its own page:
http://www.pt103.com/PT_Boat_Components_Armor.html

As far as I know, only PTs 103-150 had bridge armor installed of the 103-196 & 314-367 series.

On Dick and Al's drawing DVD, a 1943 drawing for PTs 352-355 & 374-377 shows armor plate for the fuel tanks on the outside of the hull from the outer gun'l clamp to just above the chine guard. It ran from about frame 35 to about frame 50/51. The armor was 9 sections of 2' plates side by side. Does anyone have a picture showing this armor installed? Those with the DVD can find the drawings on ELCO_Roll_5535-2_72SCAN_00514.pdf and 00513.

Jeff;
Wow I never knew that!
I know PT 308 RON 22 had these fuel tank armor plates as they were still on her, when I "found" her at Timmons boat yard in the late 1980's. They were fixed to the hull with carriage bolts, through the hull. But I never knew ELCO's carried this exterior armor. Thanks for sharing.
Take care,
TED

That's cool Ted, got this from http://www.navsource.org/archives/12/05308.htm:

The La Dee Da, which was unaltered and was still 78 feet long and in 1946 stripped condition, was found beached on the bank at Franklin Timmons boatyard in Dagsboro, DE, and was originally targeted for restoration. The effort was put to an end when the property owner seized the boat and had it destroyed, because it was deemed an eyesore for the new condo community being built.

Sad... but good job trying to rescue her.

Interesting that she had that armor, it must have been heavy as heck. Was it still holding on well?

Outstanding Jeff. A great look-see without the cabin/bridge structure.

So...that little hole in the port cockpit bulkhead behind JFK in those famous photos is a "lift hole" for that piece of armor -- not an empty bolt or fastener hole for the searchlight pintle mount.

You learn something new every day. Fascinating.

Thanks, Jeff.

I can see the lift hole but there's also a large hole at the edge of the photo that looks empty. That's where the mount would be secured by looking at the drawings. Do you guys see it the same way I do?

I think this photo shows it better. The mounting hole for the search light mount is right above JFK's hand. It does not appear that there is anything in the hole and you don't see the mount on the other side of the armor plate.

I know we're really dealing in minutia, here, guys, but...

OK...so...the little (obvious) hole in the port cockpit bulkhead in the famous JFK photo IS a bolt hole for the searchlight pintle arm...and NOT a "lift hole?"

I've always thought it probably WAS a hole for the searchlight pintle arm, but...with Jeff's CAD drawings, I..thought the hole was illustrated and explained (as a "lift hole").

If the obvious hole ISN'T a "lift hole," I really can't see the actual "lift hole" in that photo -- unless its as a tiny, almost indistinguisable black speck on the cockpit bulkhead.

I've no idea what that large hole is for, didn't notice it until you guys pointed it out. That's kind of embarrassing, I've stared at that picture often enough... It's too large for the 3 searchlight bracket mounting bolts. I thought it might be for the searchlight power cable, it's right about where the searchlight bracket was, but as far as I know the cable went along the outside of the armor and fed into the control panel on the bracket.

Here's another shot showing the 2 holes, at least I think the small hole is a hole and not an image flaw. The corner padding is an interesting detail, I've not come across a drawing showing it nor do the plate drawings show holes for its mounting:
