I looked at the Lucas Parts Manual for both 1934 and 1939 and find the 
following

1934 PARTS MANUAL
1932 Midget & coups   CJF1 for generator DPS10
                                  CJF2 for generator DPS14
1933/4/5 K L N & KN  CJR2
1934/5 P       CJR2 L17   The L17 defines the resistors used
1939 PARTS MANUAL
1937 10HP   332,177 or 336,181 (low cover on cutout)
1937 18HP 2L  337,709 (High cover on cutout)
1938 10HP Midget   332,177 ( spring cover on both covers)
1938 V    337,710 or 337,910
1938 2L S    337,909 or 337,709

The CJR series all look the same with short covers on the cutout and 
screw held covers on the fuse cover P/N 336
The CJF used the high cover on the cutout and is part number series 337
I hope this helps. The question is whether the car has 2 or 3 charge 
rates if it uses a CJ type .
