Can anyone identify these wheels?

Last year I purchased a 2008 XF 4.2 Premium Luxury, and I love it.
The inevitable has happened, however, and I a recent encounter with a pothole (mine crater) has left me with a wheel rim damaged in a way that it cannot be repaired. Needless to say, it happened the day after I had four new Goodyear tyres fitted, not the day before!
For the life of me, I cannot find a replacement rim. They are 20 inch and appear to be similar to the Sepang rims but they have 15 spokes, whereas mine have 20 spokes. They appear to be split rim, but they are not. (Faux split rim)
I have found old adverts on the interweb for a 2008 XF SV8 and a 2005 Daimler Super V8 sporting the same rims, but neither mention the style name of the wheel
I am now in the position where I may have to replace all four wheels. Then I would prefer to replace them with the 19 inch Carelia wheels that the car originally left the factory with, it may provide a softer ride,

but the new tyres only have 5,000 miles of wear.
Can anyone identify the wheel? Please see attached photo

Can't give you a direct answer, but if you take one of the wheels off and look at the inside you should see some identification marks cast into the spokes. If you're really lucky, one of these will be the Jaguar part no.

An example from my Sportbrake:

Many thanks for the suggestions
I have e-mailed SBW Wheels, but no response as yet

It is SB Wheels, not SBW and it might be worth phoning, sounded busy when I spoke to them.

Thanks almcl

I have checked for references forged into the spokes and I have found:

8.5Jx20CHe49

290 208549-RJ

03506

None of which, unfortunately, throw up any useful results on an internet search
The quest continues
