says: Holland 111-6630
27125170 above that. Something could possibly be in front of the 2 and is worn off.
Has a red dot, appears to have the transistor schematic symbol on top marking B C and E.
Looks like a germanium transistor normally would, tall and silver similar to an ac128.

I just haven't been able to find any info on it anywhere.

That looks like house numbering. Measure hFe and leakage, then you can find a circuit to use it in.

If it says Holland it's probably from Phillips :lol: For the rest I am newbie :(

A lot of stuff was made in Holland and relabeled for different manufacturers. Definitely a house numbered general purpose germanium. Treat as such and test/measure :thumb:
