When measured on my DMM the inductance of the original coil measurement 0.174mH. The new coil measures 0.019 in open air to 0.2mH when fitted on the ferrite rod. (I know I shouldn't have been, but I was surprised at the difference the rod made as the coil was slid over it.)
Attached are the details just in case anyone else ever needs them.
The new coil works just as well as the original one and peaks nicely when adjusted on the rod for the low frequency trimming and also peaks well on the trimmer cap for the HF trimming.
This has been a difficult repair, one thing after another seemed to go wrong, gut it is all working very well now.
Thanks for the advice on the coil.
This is the RF circuit, the top left coil is the MW aerial one.
Here is the finished ferrite rod.
Here is a photo of the radio.
