1920s British Straight Sending Morse Key Possibly Made By Walters

This morse key is an, approximately, 1920s British Straight Sending Morse Key Possibly Made By Walters.  Made predominantly from brass with some steel, the ensemble sits on a wooden base.

Approximate Size:

• Base Width: 14.4
• Height: 4.5 cm
• Base Depth: 7.4 cm
• Length of Key:  11.4 cm 

I'm unable to find a maker's mark but it is very similar in design to the Walters Straight Keys used by the British GPO. 

In fairly good condition, it does have wear on the brass, and some scratches on the wood.
