1n270 v cd SN 270?

Are these the same thing? 1n270 and CD SN 270? I have a pair of blue and black diodes that are really little (1n4148/1n914 size), and I kinda doubt they're germanium... But I could be wrong. They're in a bag from Mammoth labled 1n270, but look more like BAT diodes to me.

I don't have a macro lense, so can't post pictures.

What is the voltage drop across them?

I don't really know how to measure FV.

Set your multimeter to continuity. Put the black lead of the diode on the cathode (usually has a stripe) and the red lead on the anode. If it says 1, flip the diode (it's backwards). You should get a reading of a few hundreths of a volt. That's the forward voltage drop.

You'll notice that the continuity setting looks like a diode. ;)
