Hi GJ, I've seen quite a few transformer like this, sometimes the 1000v windinf is simply an overwind from one end of the HT (say 400v) windings. A good production technique to save a bit of wire and insulation.
As has been said, it could feed a C-W multiplier as the demand of EHT in the types of devices listed above is very small.
The good old VCR97 would run very well at 2.5KV
