I looked closer at
the photo on John Richards' website and it seems to me that the switch is not in the bag but has been placed on it, so there's no way of knowing the source of the switch. Sending it back, I hope.
This looks better: Scotts call the website an online autojumble, so may be more likely to be NOS; photo shows the switch inside a Lucas red bag printed with
Made in the UK. LMS Lichfield had the same
SPB200 in a similar red bag, but it's out of stock. Both of these are half the price of JR, and Scotts include economy delivery in the £14.50 cost.
