These are antique diodes. I do not know the year of manufacturer but most likely in the 50’s.
Because of age they are not in new or perfect condition the pictures above are of the actual parts. They are in pretty good condition for there age. All of the diodes will be tested with the diode test function on my volt meter before shipment.
If you are making a crystal radio you can jazz up its looks with an antique diode.
The 1N450 is not one of the more common diodes, so I do not know what was originally used for.
