Boot lock key series for Rover 90 1954

[Murgatroyd]

I'm hoping someone can tell me the correct key manufacturer and series for the above car. The number is stamped on the lever that operates the lock but I don't know the series (eg MRN etc if Wilmot Breeden). Your help appreciated.

Which lock do refer ? It probably is a WB. Do you have any spare keys to try to see which Series fits

There's only one boot lid lock. I've looked on the net and it appears to be a Union FA. As you say one can try a key of the same series. Most of my keys for classic cars are of the 30s/40s or 60s but I'll look to see if I have one to try.
