What is it ?

You have a keen eye! This is the neatest item in the grouping. It was sold to me as a British Experimental Grenade, Pre-WW1, from the Royal Laboratories. It has features in the fuze that are quite similar to the No 1 grenade but it's true origin is still a mystery.
One of our expert forum members shared the following thoughts with me before I purchased it:
"Firstly I think it is genuine for the age maybe 10 years prior to the Great War so 1904-1905 ish. That opinion is based on the brass work.
I'm not sure if it is a Royal Laboratories prototype as they normally has a design number stamped onto them.
I do have an alternate theory. In 1904 Lt Col Haldane brought back a range of grenades from the Russian / Japanese war. The RL concentrated on the Japanese grenade that had been developed from the Russian Lishin. Now the engineering of the brass top here is far better than the Lishin but the style looks similar. So this may be a Russian grenade brought back to the RL but not adopted. The heavy iron casting looks similar to the Russian stick mines of WW2 but it's clearly far older then that.
It's not one I've seen before but your seller's story could be near the mark."
I would be delighted to hear any other opinions or information which might help identify it.
