Here's one for you Gary, a 5t:
http://www.ebay.co.uk/itm/National-HRO-5T-Communications-Receiver-12-plug-in-coils-WWII-WW2-Ham-Radio-/111359913947?pt=UK_Collectables_Militaria_LE&hash=item19ed916fdb
I have one of these complete with 12 general coverage plug in coil packs in the same type of box as the one shown in the above listing, for finer tuning of the amature bands the bandspread coil packs are required, there are 4 of them, they cover most of the SW bands they have a frequency graph in both windows, the general coverage ones only have a frequency graph in the left hand window, the other window is for pencil logging, the bandspread coil packs can be set as for general coverage or bandspread on the amature bands by altering the screw positions on the underside of the coil pack (easy to do)
Mine, although working, has been modified in the past to more modern minature valves for the Osc/RF etc and a HT stabilizer valve has also been fitted, who ever did it did a good neat job, no drilling or hacking, my other one is an HRO Senior, that's the one with the plug in Xtal filter on top of the phasing unit, on the later HRO's a much smaller Xtal is used and is hard wired inside the phasing unit as is the case with the 5t, the 5t in the listing is most probably tropicalized.
Lawrence.
