I've always thought BSP. It sort of fits with what you'd expect (I do understand about Austin and threads though ). In any event, would Austin have really used a UNF thread in the 1920's? Whilst it did exist, sort of, it wasn't, really used worldwide until post WW2. I do agree that Loctite on the threads will work better than an epoxy putty when it comes to sealing. Even a couple of turns of PTFE tape would do the job better.
