These are brand new old stock from a box of a dozen we have on our shelf. New standard burners from the parts suppliers are $50 each and don't look half as nice as these brass ones. Asking $120 plus postage a pair.
I have several pair I'll part with from the box.
Here's a comparison of the brass burner and the common ones offered by the vendors.
These have all been spoken for.
Thank You MTFCA!
