Identifing NPNs

[ddragon64]

So my dad had a bag of NPN and PNP transistors.

Is there any way to identify these? At least to know what type. There are no markings on them at all.

I use one of these component testers which will give you type and pinout as well as Hfe reading and leakage. Handy to have and not expensive. There's lots of other component testers out there, more flash and expensive ones too.
This one has worked well for me so far:

Yup, I use something very similar.

That'll do nicely. Just have to find one in stock or that ships to the US.

Thanks guys!

Check Amazon, they are plentiful there

This one is in Florida, but its more expensive. Yay capitalism! Lol

But it also has a fancy case and a color screen

Maybe this will help:
