Thanks for that Andy.
The company of Osler interests me as I have been researching the entire Birmingham glassmaking industry. The fountain at the Crystal Palace (created by two other Birmingham-based companies; Chance [glass] and Fox Henderson [cast-iron structure]) was an incredible affair, but sadly destroyed in the fire there at Sydenham in 1936.
A great shame that the company went to the wall, as its creations were absolutely stunning.
