Trying to match Coving / Skirting Board - Anyone know?

[Rampage]

Hi,
I've just moved into a new house and have a couple of things to sort out.
I removed some pipe runs from the side of the chimney and now need to match some coving and skirting board.

Hopefully there should be a picture below.
Does anyone know where I can get either of these from? The coving has a step at each end. I can always make my own if I have to, but I'd rather not!

Thanks in Advance!
Chris

With the coving i have reproduced this one with polystyrene and used a sharp utility knife to cut out the groove. Works no problem.
