Nice stack Terry!
Had a Marshall half stack, very early JCM 900 series, awhile back, sold it to get cash for my move to AZ.
Looks sweet! looks like 4-10" cabs? If they are, good for you, sound better than the 12's anyway, and they can me miked to get volume. (Mine was a 50 watt head, 1/2 the old PLexi head, really, sounded AWESOME!)
Mine is a Fender Dual Showman head (1962, and mostly untouched, except for the effects loop), and a redone Fender cab with Celestion Sidewinders in it. I like it a LOT.

PS looks like a '65 reissue Strat?
