Hi Nigel, yes, it looks like the part I need. CW ordered the part for me so I think I will just improvise something until it will arrive. I purchased in the past from SJS (not Brompton related) and was very please with the service and shipping.

BTW, just looked Brompton spare part list at SJS, wow! this is the most extensive folding bike part list I have ever seen (mostly BF, Moulton and Dahon). Not to mention the inventory and expertise of the local dealer. I am impressed.
