First class service from FromJapan.co.jp and Fedex.
Following Foy(not Fox)'s suggestion I approached FromJapan.co.jp to get some stanchions for one of my non-RDs.
Buyee would not help as the stanchions are considered to be suspension and may contain oil or gas.
FromJapan were a little less generic, and after investigation understood that they were simply pipes with no oil or gas and so agreed to ship them for me.
Here's the timescales.
07/03/23: I ordered and paid for the stanchions (not shipping)
FromJapan ordered the stanchions from the vendor.
10/03/23: Goods received in FromJapan's warehouse.
FromJapan advised of the different costed shipping options, I opted for Fedex International at circa 33 GBP. There were much
cheaper options for surface deliveries.
11/03/23: Fedex picked up parcel, from Japan, transported to China, France and the UK.
16/03/23: Delivered to my door.
Fedex operated a system whereby they pay the customs fees and then passed that charge to me plus circa 20GBP for the privilege of using their system.
The packaging was excellent: I believe this was the original packaging from the vendor, FromJapan simply re-labelling the parcel.
The total costs were slightly cheaper than having the old stanchions re-chromed, but I didn't really want to have the bike sitting on stands in the garage for the duration of the re-chroming exercise.

I was expecting some grief with this purchase, alas everything went surprisingly well.
