A very strong burner once warmed up although it seems prone to blowing itself out. Nonetheless a lovely stove. It appears to have had a new control spindle and packing nut. As I read in a previous post the SRV built in the tank is clearly not intended for user servicing but appears to be working fine at the moment. I'm undecided as to whether I should do a restoration on the case with this one. Any help with dating would be appreciated.
