I think one or two Startrites have the ACM badge if you look for the Italian sticker at the back, well they used to.
Wadkin's still making stuff (not sure if still in the UK though, and seems only 3 phase which is odd for a wee saw like that.
That E400 would be quite flimsy at 125 kg though.
The Italian machines that's not 400 but 440, or 540 are usually a little heavier grade of ACM frame.
Look up SNA vs the heavier SNAC in the range.
Possibly quite a bit more difficult to source tires for the snaC
Maybe akward, silly, expensive and difficult
(if you wanted it done yesterday kinda thing)
If you want British but still just about handleable...i.e no forklift needed.
Some of the Wadkin's, the Multico's or the Startrite's might be available refurbished.
Parts are normally interchangable like guides (Wadkin & Multico take GL456)
Look at ScottandSargeant for instance.
Wheel bearings are standard on all saws made these days.
V belts on machines of this size available at automotive or lawnmower places.
Nothing else to worry about on a bandsaw really.
I would still think I was being a good sport buying refurbished machine, or even buying the parts to restore one the same.
