You guys are just great. I enjoy the ability to talk turrets and parts for our projects with like-minded troops!
SARCO in NJ is a great company to deal with, guys. Talk with Dave - he's their resident MG expert and they can set you up with original and replica barrel shrouds for the 50 cal M2 and M3 BMG. They've done some nice reproduction work. Nothing much to a barrel shroud to make a neat replica to hang off a turret or nose of the airplane, but they are an enormous amount of work to do without a CNC program as they are just darn labor intensive to drill all those holes, parkerize, etc. Anyway, they've always come up with neat stuff for me in the past. Original stuff is getting kinda pricey - be forewarned. I need 9 MG replicas alone for our PV... and that's just ONE lumpy a/c.
OK - switches that I need - anyone with 'em, please keep me in the loop! My WWII ErCo manual is a good one but it doesn't include an IPB with part numbers. My Klixon circuit breakers are 15 amp and 20 amp (and I CAN use radium tipped ones if ya'll got em.... my first panel doesn't have 'em but the book shows 'em in place). The four other single pole switches are 15 to 20 amp rated, and the main switch is probably 50 amp rated (the big relay inside the box is 100 amp). I intend to run my turret up but will not put the same load requirements to it that the Navy did back in the day...
Albert - have the guys PM or respond this forum working on the ErCo nose. I have many, many electrical and hydraulic spares to share + manuals. Bought them in a cache not on your scale but in "barrel form" years ago that came from scrappers working out of the former Litchfield NAF, PHX. Oddly, they never saved the turrets but saved the electrical and hydraulic pieces. I have two of these ErCo ball noses for the PB4Y-1 and -2; they made about 3K total on the SH models. Manufacturer was Engineering Research Co of Baltimore, MD.; same guys who ended up building up the Ercoupe 415 aeroplane for us after the war. They built some beautiful turrets.
I got lucky with my nose turrets, as Tucson and PHX were final assembly plant/install centers for B-24s and -4Ys here during the war. I suspect my turrets had been NOS units sent to AZ for fitting but never made it as the war ended. They ended up with scrap dealers; one paid $25 each for a lot of 5 of them hoping to toss them into the furnace and was PO'ed to discover electrical and hydraulic parts, armor plate and glass and the like and not 100 percent aluminum. I have a Palley's Supply catalogue from the early 1950s with turrets like these - NOS in boxes - for $250 each. Palleys and McBride later sold B-24/B-17 ball turrets new in boxes for as little as $100 each as late as the 1960s....
I have a list from GLM (Martin) detailing the dash numbers of the 250 upper turret particular to specific aircraft type. I can PM it to you or post; most people will be bored silly with this specific data stuff. Most Martin 250s look alike to one another - little differences as you know made a BIG difference to the a/c type they were mated to, the one big thing being the fire interrupter drum/profiler. The other stuff was varied between Army and Navy contracts for the need for oxygen systems, commo systems and of course another big deal - sighting systems.
I lust after a lot of your Martin goodies, too - my goal is to have the Martin in our PV-2 fully operational as well! I'm pretty close...
K-25 camera door is a nice find. Most of the remaining civil registered PVs have had that door removed as it got in the way of easy sliding of a spray tank into the a/c. Most operators removed them or cut the camera mount off and faired the glazing window opening over with sheet metal. If it doesn't irritate you I'll ID any of the items I can for you in your photo list. I'm certainly no expert on everything, but some things are pretty familiar to me.
I am hoping the ErCo turret I have (at least one of them) will end up on the PHX -4Y. It's not my bird, but belongs to a friend. Right now he is overwhelmed with costs concerning getting the a/c airworthy and down here to PHX, and it's his first warbird. The restoration part of the project is still daunting to him as he's been spending money on something he has yet to play with (welcome to warbirds, eh?) and he hasn't really had time to look into the future. Fortunately for him he's got access to a cache of the majority of the turrets for said project in my hangar (four out of six). My hope is that 15 minutes in L or R seat will fuel the disease and he'll give the nod to the restoration of said beast and will want to add back her original warts and bumps where they belong. We'll see... that's my secret Christmas wish.
I have just a few operational spares from the Aero series P2-V Neptune/Mercador but you are welcome to what I have (electric motor systems, gearboxes, etc.). I decided long ago to concentrate on WWII turrets specific to my projects or ones at hand and never got into the Neptune, though I almost bought one a few years ago. And do pass on to the boys about the Martin Navy nose turret, too - yeah, I have some internal spares... happy to help.
