Is this a Hawker Nimrod II Spade Grip?

Hello all,

I have inherited a spade grip from my grandfather who worked as an aircraft technician during WWII. As a memento of his time served, he was given a spade grip which has since passed down into my possession. I have been trying to identify the particular model aircraft it was from but I am not knowledgeable on the specific part numbers etc.

The spade grip is in immaculate condition, I don’t think it has ever been used. It bears the BSA stamp alongside these other identifiers:

900/34
MD2B1 (I think, not quite clear)
BH7
BH7 is also stamped on both triggers.

I have come across a number of photos of a Hawker Nimrod II cockpit and the spade grip looks identical. Can anyone identify this item or recognise any of the identifying marks shown in the photos below?

Any ideas on sale price for such an item would also be useful.

Many thanks for looking and for your help
