Ey up folks. I asked last week if a tilley grill would fit a bialaddin bowl fire and podbros was kind enough to reply and say mrcod had recently tried it so I immediately ordered one from Julian Shaw. Its just landed to and I've tried it. A bit of a week to the mounting lugs and it fits a treat and looks shiny too. A vast improvement on no grill at all. Thanks again.
That does the job, but it's upside down, the wire hatch is meant to be at the top, it's for ease of access when the wind shield is being fitted and removed and the link below shows relevant information. Tilley R1/R1A - Draught shield dimensions
Ah right. Cheers for that. I did wonder what it was for. I have left it bottom for now as I don't think I need to use the hatch. It's less noticeable at the bottom.
