Here's what W. Green says:
G-2, normal loaded weight 6834 lb, DB 605A 1475 hp at take off
G-6, normal loaded weight 6940 lb, DB 605AM 1475 hp for take off (no MW 50)
G-6, normal loaded weight 6940 lb, DB 605AM 1800 hp for take off (with MW 50)
G-10, normal loaded weight ???, DB 605D 1850 hp for take off (B4, with MW 50)
G-10, normal loaded weight ???, DB 605DB 1800 hp for take off (C3, no MW 50)
G-10, normal loaded weight ???, DB 605DC 2000 hp for take off (C3, with MW 50)
K-4, loaded weight (clean) 6834 lb, DB 605ASCM 2000 hp for take off (probably with MW 50)
Normal loaded weight of G-10 should be very close to G-6 figure, I believe.
