Back in the day, Radio Shack would sell a grab-bag of random and cryptically marked transistors. No data sheets included. But a hobbyist willing to spend the time could save some money sorting through these. While I can't imagine anyone doing this today, I see that the "FREE with coupon" Harbor Freight DMM still offers the so-called hFE transistor-test function which allows you, in effect, to determine the CBE orientation of a transistor as well as its polarity (NPN vs. PNP). Here's the meter set to hFE mode with an NPN with the EBC orientation showing an hFE (current gain) of ~200.
Unfortunately, this is NOT suitable for working with FETs.
