It happens all the time. So much so that I have determined that the best way to find an original part is to make it and the install it in the Harpoon.
One of the best ones recently was I busted my backside to finish up the radar modulator rack so I could install the modulator before I left on a driving trip around the country.
I was in Tucson and scrounged through some C-117's to get the interphone jack boxes. They were real crusty and it was about 110 degrees outside the fuselage and a wee more on the inside. I hit up several of these hulks over several hours to get a bunch of the boxes that will need a full rebuild. Crusty is better than nothing. Later, I stopped at Albert Styx's turret parts emporium and guess what he had? New old stock interphone jack boxes. I was floored to find a radar modulator rack also new looking and a set of radar racks for the receiver and the power supply. Boy did that modulator rack look a thousand times better than the one I hacked out of stainless steel.
Thanks Albert!

Sorry about the photo size as it was mooched off of eBay

That beautiful piece puts us closer to completing and operating our AIA-2A interphone system. All we are missing now is the shock mount for the amplifier which I will find shortly after I make one...right Rob?
The other thing we need is the dynamotor and its mounting plate for the RL-24C. Anyone have one of these in the basement, garage, shed or hangar?

It has a blue data plate that says DYNAMOTOR UNIT FOR RL-24C.
I have other dynamotors that are close and would do until I can find the right one but they only put out 250 volts. The AIA-2A needs 330 volts.
Anyone?
Anyone?
Bueller?
