Steeden stopped being a born and bred Rugby League brand in 1995 when Grey-Nicolls bought them out. These days Steeden's are pretty much made in the same factory's that Gilbert's are made in India.
Apologies to have to correct you, but the Steeden factory is a completely different one to the Gilbert one and is in fact in a different city.
The Steeden is still the players choice throughout the world and remains a born and bred Rugby League brand. Steeden are in it for the long term despite what rumours you may have heard or read, and progress is being made as we speak to allow Steeden to continue as the No 1 Rugby League ball in the UK.
