I don't like the look of it either.
I've found an RS 100:1 probe in my drawers. 489-734 which no longer exists in the RS catalogue. The data with it was issued in 1984.
There's a curve showing it derating from 1200V at 1MHz to 200V at 10MHz. I think I'd be willing to trust it though I'd prefer to switch off, connect the probe and switch back on again if I was getting near the limit in (say) a transistor line timebase.
It would also be useful in quite a few valve circuits as my scopes only go up to 5V/cm, hence 50V/cm at the tip of an ordinary 10:1 probe.
