A friend of mine's son inherited an old Marshall a few years ago and he just chucked it in his attic, so I offered to take a look to see how much work it needs, and to balance that against potential value.
I think it's a 1980 JMP 2104 50w 2x12, basically the combo version of the 2204 head.
Obviously it's covered in shite, half the logo is missing and an input jack has either been removed or dropped inside, but it all seems to be more or less intact.
Any thoughts on what it might be worth after a quick refurb? I need to give him a realistic idea on what he might actually get for it in order to decide how to procede.

So... if the plan is to sell it, play the speakers enough to know they're working and don't have any issues that are about to emerge.
When I looked a couple of years ago (was contemplating buying it off the singer's uncle), the combos sold for less than the equivalent heads - £500-£650 or so. Don't know if the market's changed since then

I intend to clean it up, fill it with known good valves and test it with a different cab to start with.
There's some sketchy looking wiring on the speakers, so I'll treat the amp and cab as separate entities before I fire it up as a combo.
Time to make some spiders homeless!
Stating the obvious but those mains filter caps seem to be the originals (1980). They are likely to be shot, particularly if the amp has not been used in a long time and should be changed, probably before you even try to power it up. The output valves are knackered by the look of them.
I'm sure @ICBM will be along to tell you that spiders are conductive! so be careful in there.
I think that needs a proper going through to sort the issues. The valves should be tested but might be OK depending on how hard a life they lived before retirement.
If you are doing it yourself, fire it up gently on a variac. Those caps will likely be dry and ready to explode. Or just change them anyway to be sure.
I can't help on the current value - I think I paid £120 for mine, but that was in the early 90s!!

Any recommendations on where to get filter caps? I'm good for valves and speakers.

BTW, @p90fool, I have some F&T 40+40uf 450V radial caps, if that's what you need.
Look like this (but 40+40uF and 450V):

But as already said, don't even think about turning it on. It needs to be fully inspected, tested and powered up under properly controlled conditions by someone experienced, or it may suddenly be worth a lot less. One valve is definitely dead, the other looks quite unwell... and yes, spiders (and their webs) really are electrically conductive!
