That looks like it Maurice. So it was named after an instrument that Riley's possibly sold. Looking up on google (https://www.pianola.org/factsheets/angelus.cfm ) it looks like it was a pianola made by the american Wilcox & white Organ Co. Wikipedia (https://en.wikipedia.org/wiki/Player_piano ) say it was introduced in 1896. Therefore, if this is correct, and the name of the Hall does come from that instrument, then it must date from after 1896, possibly just before the recital described in the cutting. Rileys seem to appear in the mid 1880s, but possibly the Hall was a later addition.
