FH - speedometer

The chronometric speedometer that appeared with the FH kit is definitely not Ariel – I was told it is from a police spec AJS Model 31 CSR! The rim has a 3/8" piece removed from it which looks very tidy, definitely not a bodge – maybe it’s to allow a police workshop to remove the rim for recalibration easily? I have no idea if it works or not. 

So – in order for it to become a S467/195, which I believe it needs to be to suit my ’58 Huntmaster/FH, it will need:

• An overhaul, including resetting to zero
• A new dial
• Probably a new rim.

Lastly it looks like the male thread for the lamp is spinning in the case – I guess it was swaged in or something, so that will need sorting out too.

As usual, I sent it to Russell Smalley at Chronometric Instrument Services - he's done all my speedos since the SQ4. His quality of work is excellent and very fairly priced.

It came back in about a week, thoroughly packaged:

It's got a used dial and needle, so that the appearance is in keeping with the odometer wheels. It's had a mechanical overhaul, new seals and rim, and a new bulb holder thread swaged in to the case:

Here it is going into the dashboard:

There's a stainless bracket I made for the indicator relay - which in this position makes it fiddly to fit the cable. I think there will be a bit more development needed here!
