Howdy fellow enthusiasts... So I came across this at a local auction house, and I've been told it has a lot of interest... (which is great given I'm yet to a. get a speedie and b. I'm slightly skeptical of this), ha! So it's claimed to be a 1970, -69 case back, dial looks to be -69 through -71. Looking at the movement it dates to a 1972-1973. The 1039 bracelet whilst not impossible, is unlikely from factory. It's estimated to go to 2-3k Australian which. What are your thoughts?
