I recently purchased a Hornby Brittania (Lord Rowallan) through mail order. On unpacking the model I discovered that the speedometer cable while attached to the rear left driving wheel was unattached to the locomotice body. A close up picture included in the most useful MRF review reveals approximately where the cable attaches BUT how does it do so? The end comprises a piece of chromed metal which has a bend and a pointed corner, but it is not obvious (at least to an idiot like me) how this locates with the plastic of the locomotive body. Having considered the possibilities, I suspect the metal may have formerly been glued directly to the plastic. If so, how is it orientated and why the pointy bit? Any advice will be most gratefully received.
