R-Core transformers for 1U boxes

[pvision]

In my (seemingly) eternal quest for transformers that will fit in 1U devices, I've been looking again at R-Core transformers. There are a few that fit the bill - here's one example that is 39mm high

These are very obviously Chinese trafos imported & resold - they are also on eBay ex China with the same photos - but I'd like to find a supplier in the UK if possible

Any suggestions?

I used some for an RS124 build which were pretty slim. I didn't put them in a 1U case, but the cheapest place I found was in France, at the time. it was actually the place you hvae linked to. This was just over a year ago, so I didn't get fleeced on imprt duty.
