Needed: A Commemoration Plaque

While doing some research, I came across a letter written by Ze'ev Jabotinsky to the HQ of the Jewish Legion in London at the end of October 1917 while he was with his troops in England:

I found out that while Chenies Street 

is marked by some memorials and history, the fact that the Jewish Legion HQ was at 22 Chenies Street is not marked.

I think a small plaque along the lines of:

During World War I, a building at 22 Chenies Street

served as the Headquarters for the Jewish Legion,

a force of over 5000 Jews who served in the

Royal Fusiliers and fought in Palestine 1918

Isn't that a grand idea?

Who, then, will help?

P.S.

By the way, as I included in a previous blog post, there is a film clip and it would be wonderful if the building Patterson stands in front at around 1:30 and at 2:12 Jabotinsky appears was that Chenies Street building.

Is there anyone who could check newspaper archives and see if there was a report which mentions the parade which took place on Monday February 4^th 1918?

It may have been The Pavillion Theatre in Mile End Road (which actually stood at 193 Whitechapel Road, near the corner with Vallance Road).
