Good news, bad news. I have the starter mount & the front cowl but not the mounting legs.
The Wren 54 mounts the starter to the inner cowl section, the Wren 44 to the front cowl (as I have one of those)
but this cowl has no holes where it would have mounted.

The legs appear to be machined from one piece of aluminium with a male thread to screw into the starter holder
at the top & threaded holes in the other end for the mounting screws.

Let me know if you need it, another reader has PM'd me to say he will take it if you don't.
