I am trying to make up a Speedo cable and  Tacho cable for my 1924 Amilcar. The items at each end are as follows.
SPEEDO.
# Drive end. Projecting from the drive fitting on the Tailshaft is a 11.3mm diam. sprindle, and projecting from that is a 6mm diam. smaller spindle with a small hole for screw fixing..
#Instrument end. Projecting from the speed is a 6mm diam spindle with small hole for fixing (see attached photo.
# So I need a flexible cable with inner cable with fittings attached which will connect at each end ton6mm diam spindles, and with an outer cable which has some way of anchoring at each end.
TACHO
# Drive end. The Tacho is driven from a fitting at the end of the camshaft with a 2mm wide slot. See attached drawing. So the fitting at the drive end needs to have a 'blade at its end of 2mm thickness and 7mm wide.
#Instrument end. Same as for Speedo.

Looking at your catalogue (Spring 2012 edition), page 50, the item at the top "Speedometer End" seems to be what I need for each end of Speedo Cable and Instrument end of Tacho cable. My instruments do not have any form of threaded connection. The instruments are Jaeger. But I'm not sure which of the 3 sizes listed in your catalogue would be appropriate.
For the drive end of the Tacho cable, the second item on the same page may be suitable, Speedometer Cable and Housing. But of the sizes listed, I'm not sure which would be appropriate.
Ultimately, I will need three of the Speedometer End items and one of the Housing fittings, plus two driving cables of about 1.5m length each and two nickel plated outer cables.

Can you advise on sizes, and if you think your items may be suitable or capable of adaptation by me to suit my requirements.
I think the best thing is for me to purchase from you, one each of the two end types, a short length (say 300mm) of inner cable, and a similar short length of outer cable. With those, I will be able to see if I can make it work.
Please see attached photos.
