Just realized I had this question in the wrong place. So here goes. I have been asked to return a Marshall 4x12 to it's original specs, but have only found conflicting info thus far. The cab is loaded with UK greenbacks, three dated as Dec '72 and one dated Jan '73. It has a plastic handles, no corners, gold piping top and bottom, and bronzed casters. Now the odd part, the tolex is red and the grill cloth is salt and pepper basket weave with white piping. So far I've found conflicting info about this period, Which is why I'm turning to you guys. The baffle has definitely been messed with (3 or 4 different types of screws holding it) but the tolex doesn't show any signs of being replaced. My guess is that the grill should be the large checker pattern, but was red even an option at this date? Any help would be much appreciated.
