ODP: transistor question

[Roman Sowa]

BF245		D-S-G
BF244		D-G-S
and they are the same electrically.

'A' has threshold about 1.5V, 'C' about 7V AFAIR

When I was choosing 245s for VCO, I found wide variety
from less than 1V to 4-5V. They were all not clasified to
neither of ABC classes

Next I came across our beloved BF244/245 Type JFET.  They seem to be the
same, but the 244 has a strange pinout.  Class A,B and C seem to name
different groups of threshold voltage.  If you buy them without class
character, you can get any threshold voltage.

Is this correct? The data sheets are a bit implicit.
