Specially made for King Cog and exclusive to him are these longer knobs for all Tripmasters and Twinmasters. Ideal for navigators with short arms, or instruments fitted a little further away from the perfect position, these quality parts fit all Tripmasters and Twinmasters with no modification other than removing the old knobs. They are made of brass, the screw threads will not strip in normal use like the original Halda knobs, and they give a nice positive action because the heads are larger.
They are anodised black to keep them pristine like your Halda will be if King Cog has restored it!
The price for one is GBP 9.00, USD 17.00 or EUR 14.00
The price for two is GBP17.00, USD 32.00 or EUR 25.00
The price for four is GBP30.00, USD60.00 or EUR 45.00
Postage is extra and you can specify any combination of pointers or zeroes on the heads.

REPLICA HALDA LEATHER GEAR CASES AND HOLDERS
Now at last a new stock of replica gearwheel holders and leather cases has arrived!
Only available from the Haldaman, perfect replicas in top quality materials of the original Halda accessories.
Firstly the chrome plated and anodised holders which accommodate a complete set of 33 X wheels and two Z wheels, everything the classic rally navigator needs to calibrate his Twinmaster or Tripmaster. Two Z wheels are normally all that are necessary, one for the miles and one for the kilometers calibration.
Now the leather cases which hold the complete gear set on the holder, with room for a small bag containing the other 7 Z wheels if required. The originals are extremely rare although some ex works navigators are known to have kept theirs after Halda gave them to favoured co-pilots. My replicas are almost identical apart from being new, made by an expert saddlery firm in tough black leather and stamped with the Halda logo in gold.
Prices of holders and cases are as follows:
Holder alone: GBP 35.00, US$ 70.00, EU 50.00
Case alone : GBP 55.00, US$ 110.00, EU 80.00
Special discounted price if you order case and holder together: GBP 85.00, US$ 170.00, EU 125.00.
Strictly one per customer only!
Complete set of X & Z Wheels
118-150 X
16-70 Z
£450.00 instead of £504.00
I regret I am out of stock temporarily of many X wheels so cannot supply complete sets at the moment.
These are almost exact replicas of the gear cases and holders that are very rare. The cases were given to works navigators and a very few have surfaced. My replicas are very strong hand stitched leather with the Halda logo stamped in gold, just as the originals. An ideal gift for the navigator who thought he or she had everything! Holds a complete set of 42 X and Z gear wheels. The cases are a very reasonable GBP 55.00 each, considering that they are individually handmade and are bound to impress all the other competitors, besides being essentially practical and useful on an event. The holders are chrome plated and hold all 33 X wheels and two Z wheels (one for miles and one for kms) securely so they will not roll around in the car.Just a holder costs GBP 35.00 and with a complete gear set is GBP480.00.
COMPLETE GEAR WHEEL SET WITH CASE AND HOLDER.
There are 33 X wheels and 9 Z wheels in a complete set and bought individually they would cost £504.00, but you can buy a complete set for only £450.00. Moreover, if you want a gear case and holder at the same time you can have all these for a total of GBP 530.00 for the set of everything a Halda user needs!

Losses in the mail !!
In the last two months two valuable packages I sent by airmail have gone astray. Perhaps this is a new policy by Royal Mail, to lose a certain percentage! Anyway I am now going to insure every package I send out to Europe and beyond, so that a signature will be required on receipt. I will have to pass this on to you but at least you will be much more sure of getting your parts.
USA customers please note: For some reason it is not possible to insure any packages sent by ordinary airmail from the UK to the USA although they can be sent recorded, ie needing a signature.
For really fast secure service you need to use Fedex or UPS, which can be expensive.
