During the 1968-69 season (and quite possibly for longer) the team trained at Cooksey Lane, Kingstanding. I know this because, along with others, I was a winner in a Co-Op painting competition (very fortunate because I've never been any good at painting!) and part of my prize, along with a 1968-69 season ticket and a tour around Villa Park, was a trip to watch the players train at Cooksey Lane.
I'm sure it was named after Bert Bond, and Doug bought the land from a local farmer. With his own money, according to Doug.
I remember reading somewhere that the club begged or borrowed facilities from local factories between the training ground being sold and Doug buying Bodymoor Heath. Hardy Spicer in Erdington/Pype Hayes rings a bell as one them but I may be wrong.
