rough value of vintage marshall cab?

[fuzzking]

i'm thinking of selling my 4*12 cab locally (not on the board, so please don't consider this an advertisement), but i can't figure
how much i should ask for it. i haven't seen one of these on the bay or anywhere else lately, so i can't make up my mind.
it has the metal handles and light brown cloth, greenbacks, (i assume it's pre-'71) - a bit battered here and there, part of the
plastic logo is missing.

any rough guesses? i know they'd be cheaper in the US than here in EU, but just to get a rough idea before putting it on sale.

:-\

erm other way round..old marshall stuff is more expensive in the US than euro usually.
