As above
Lamp, filter caps, screen resistors replaced. Quite why the loom was pulled apart - who knows.
The head box looks ok although it should have the plain domed feet and the levant (tolex) looks a bit shiny in those pics but probably just polished up for sale.
I think everything important is there. I would be tempted to restore board to stock (ditch the MV) an attenuate.
Oh and it is a Rosemary.

Yep, revert to stock and a Rosemary. I'd go for it if price was right.

As the others have said, I agree that the transformers look to be original, and it's in good shape with no irreversible mods, apparently. Good that the caps were done. Interesting that one speaker jack (out of the four) was removed and plugged. I have a '73. I paid 1400 for mine and I paid that much only because it was also not an amp that had no irreversible mods. (No extra holes drilled.)

A 1959 is REALLY uncomfortable to be around when it's cranked up and sounding its best. I don't mind an MV mod for that reason. But if I were you I'd have that MV mod transferred to that covered up fourth speaker jack hole on the back panel and restore the input jack quad to original.

Your chassis is pretty dirty. It'd benefit from some time spent cleaning it. Odds are it'll never be shiny but you can get rid of the accumulated dirt easily enough.

Thanks for the inside photos. Now I've seen insides of a '71, '72, and '73 example, so I see how things changed. It looks to me like the perf board changed to the first ST1 board at the same time the extra power supply board was eliminated.

The loom was probably pulled apart to convert the output transformer to 220V, the guy bought it on Ebay in US.

Inside your chassis, it's pretty clean. Outside, it's in the normal range for an amp that has spent most of its time with the back cover removed.

Mine was worse, cosmetically speaking. Your panels (front and rear) are in fine shape. I'd say your amp is overall in very good condition and should clean up very well. I suspect you're getting a very good deal.

Turns out it's a 1973. The 3 looked like a 2, but as it's a serial number with a E, should be 73. Moving the MV to the back should be an easy fix. Eliminating it on first sight requires two new resistors.

If the serial number ends in E, it's a '73. Mine is 5589E which is 1973. The transition to the first edition ST1 board happened late in the year. Mine has the early ST1 board.
