Gday Mick
I grew up with Chester cookers, Pabda from the Viceroy is spot
on with info on these traditional catering ranges, but there are plenty
of refurb places in the UK where if your lucky you can pick one up.
But not forgetting your buying a well used antique .
I remember a friend had a problem when he set up a new kitchen with an old Chester.
Something with the Gas Board and their new regs/ H&S when installing meters and supply. Cost extra to install.
The usual modern stoves that you see in my BIR videos are of two types,
1. What I call the cast solid tops, with removable spinners and open burners.
2. The Frame type, with removable grid tops and drip trays and the same open burners.
Your choice, as companies make them up to your requirements.
My restaurants have used various engineering companies in the Midlands
and some have gone cheapo refurbs.
Probably one of the best websites to get your head around is SylhetWelding, which make everything you need for your Bangladeshi BIR.
I'm not saying you should contact these Bangladeshis, but your Indian Chef should be able to communicate with them OK.
