Need help to get a vintage Motorola transistor: MA series from the '60

Hello there, I am from Argentina, I am 32 years old and I am looking vintage Motorola transistors. I know this is the right place to post this given the amount of members and experience of them.

I am looking for Germanium transistors from Motorola, codes MA200 thru MA206, MA286 thru MA288, MA881 thru MA889 and MA909 thru MA910. They are very old, from the datasheets I was able to get approx 1969 or later. They are TO-5 encapsulated ones.

I need several of them, new, used, will be great both ways. Or If you know which equipment was using them. Any lead will be help me. I will really appreciate your time. Don't hesitate in contact me if you know anything about them.

Was able to buy a MA288 one ;D, still looking for me. Any help will be welcome.

Bump!bump!

Perhaps no one knows.

What about using more modern equivalents in a similar package style?

because I was doing a cosmetic restoration work, the device won't have to work. It does not matter anymore. Thanks.

Are you still in need of these?? ..IM me as I may not look here for a while.

what are the dementions of this transistors ? I have a nice collection of old electronic parts, I will be easy for me to find if I know the size of it.
