I did have some (kinda) OC71 transistors, but they were more
modern-looking than the originals; they were called OCP71, I
think, and were blue plastic at the bottom, and then they had
the glass bulb filled with gel. They were about the same size as
AC128, and also had long bendy wires on them.

After they filled the OC71 with opaque gel so you couldn't scrape the
paint off and use it as a photo-transistor, they came out with the
OCP71, where the P stood for Photo. This was again filled with the
clear gel, and I think it had a small lens moulded into the side to
help gather the light.
