I found the grill.
I don't know how you ever bought just the grill for $25 unless that was 30 years ago. It finally occurred to me to look it up in parts fiche drawings. It is $65.21, but it is obsolete.
Anyways, I found it for new, for less than that, including shipping. I am sending you the link by PM. They have more than one, so I have ordered mine, and you can get yours too. They are being made in Great Britain -- and the delivery time is 33 to 37 days!
