Hi folks.
As well as a possible (hard to prove) Jack Alan weight, this one could be one of the range of "experimental" items made at Strathearn in 1979/80.
Several of those "experimental" weights have the 'white thread cushion' (techy term eludes me right now.) And several are known to use canes originating from the Ysart Brothers (Vasart) period - which I think is the case for the outer garland.
This is an interesting weght and more clues to its actual maker may pop up in the course of time.
