Picked this up on eBay last week, looks to be an exact copy of Weber's CnT ring
Looks like a gas Happy Cooker on the box so I presume it's from the 80's
Price tag of $26 which is what I paid for it on eBay
Made by Bar-B-Chef in Taiwan and imported by GLG which is an outdoor leisure company based in Sydney who import BBQ accessories for the BBQ Galores chain stores here in OZ.
