I need a manual for my Softline Diplomat Gas Oven, please?

Can anyone please help me to get a copy of the manual for a Diplomat Softline built in Gas oven. I cannot help with a serial or model number as the specification plate has been polished clean.
I just moved into this house where the oven was already fitted but no manual.
I think the oven might have been supplied by MFI but of course they no longer exist.
