Good grief! The ingenuity of the modeller! Good solution Chris, and I'm happy to hear you are feeling at least a little better.
Now, how come you live in a model shop? I take it that IS a model shop, with all those kits!
BTW, I've posted another 3 useless pics of '410's in the 'other' 410 thread. Two of them show the WrGr tubes, and I have a good close up of the latter also, if you think it will be of use.
Terry.
