EN 1.2210 in Europe. DIN 115 CRV3,1.2210 in Germany. SS2240 in Sweden. BS4659 BO1 in UK.What is the European (ISO?) designation for silver steel?
Hello David,Starting with first on the right, then bottom to top: 29/19, 24/24. 22/26, 20/28 which means this is a No. 5 box. This would be the usual Grey Flash ratio for the non-KS magnesium box. The aluminum No. 16 box was provided for KS Flashes.
The reason for chicanes is to show St John’s Ambulance Brigade where to place their vehicles.UPDATE
I have stripped the box and on the layshaft starting at the drive end I have 21 24 26 28 which using the table supplied by David gives me a No 3 box
to make it a No 5 box I shall need a 29/19 (some hope!) I note a 'standard box' is 30/18 which if I have got things the right way round is a little lower at 2.78 than the No5 at 2.13*. So now I shall raid my store of Albion boxes and strip one down to see if its any good (I will be getting good at working on these boxes soon...)
* That wont be too bad because of the stupid chicanes they have added to the UK circuits to slow down the super bikes which the ACU in its 'wisdom' force us to keep for reasons unknown to man for Historic racing as well.
