Hi Russ,
the original stove is manufactured by
techimpex in Italy
Spareparts are available at
SVB or anywhere else.
I have replaced mine completly with a
Dometic. Offers additional electronic ignition, and the upper side made from glass, with could be kept clean easier than the techimpex (says my admirality!). Was a little bit tricky to mount with the hinges, but now looks perfect!
