A batch code usually means its from a certain factory production run which means there is a good chance the gain will be similar .
We already know its a 2SC2240 in TO92 design audio low noise BJT and GR indicates its gain ranges from 200-400 @2ma at a Vce max of 120V so would be ideal at an amplifier input --Ic max is 100ma.
Usually measuring the gain of a pile of them you could get two that were a very close match and that would help make an easier balanced input circuit.
But no Ben I have not got the coding you want.
Batch codes are useful to manufacturers in case of customer complaints , the customers are usually the electronic industry not your general public.

Hi,
That's all very helpful information. I'd actually thought that it was more or less a date code to which I could read and use when looking at other Toshiba bjts, so as to get an estimate of their age in their production span. Or even as important, to spot a fake.
Your input was much appreciated, thank you.
