Looking for Early Metal-Can LEDs (1967-1971) Like TO-29 Solid State Lamps for Collection

I've been scrounging together some older LED's recently and find their history pretty interesting. I'm searching for some from the very very early days (1967-71) of LED's or Solid State Lamps as they called them back then.
I'm hoping there's a few people out there who's held on to some of these early emitters because they thought they were pretty cool even though they are primitive by today's standards.
My plan is to eventually make a history of LED's website to share the stories and some quality photos of the devices.
Anyone have some metal-canned LED's? The early ones were often in modified transistor cans (TO-29) and often came in a fancy plastic case. I've attached some photos of the types I'm looking for.

If you can help it'd be greatly appreciated!

Ah, those were the days, when your component came in its own case!Sorry, I do (somewhere) have some LEDs in metal cases similar to the above but they are more modern types, not the original ones like the above.
But one thing you could consider is to find one of the old LED watches.  You pressed a button to display the time for a couple of seconds.  I went through a couple of them when they came out but they were soon overtaken by the much less battery-hungry LCDs.

Yeah I have to admit even the Monsanto disposable packaging for their early LED's were nicer than I'd have expected. The SSL-1  did cost the equivalent of $70 bucks when it came out so you'd want it to be safe in transit. Here's the press release for the SSL-1:http://www.ric.edu/faculty/rpotter/temp/ge-pressrelease.pdfThe 7-segments and alphanumerics are very cool; however, I'm trying hard to stick with individual LED's so I can show the linear development through all the colors. I have a blue LED from the early 90's that's super dim but is a good example of when manufacturers finally figured out how to make blue (white was the last color to be cracked - in the visible spectrum atleast.)I have come across a few companies that seemed to still make hermetically sealed LED's like this. Must be for legacy systems or something? Dig them out and take a look at them. The canned ones usually have a clear window (opposed to diffused) so you can easily see the die and jumper wire.
It's been described as an unusual hobby but I have heard some great stories on my hunt. I've even corresponded with the inventor who worked at GE as well as the inventor of the first yellow LED. It does indeed sound like it was an exciting time to be an electrical engineer!

Don't expect this one is very old but it is weird in that the end is 3/4 of a sphere on a smaller diameter body. The flange part is much chunkier than modern 5mm ones. The internal structure is not like modern ones.A rubber ring helps the mounting. The positive wire has a "cat's whisker" to the middle of the chip. The insulation on the wires is moulded into the epoxy.Does not seem to work.
