Hi
These are from the rear seats of the early HPE and an are form of cup washer, however I have not been able to find any like it. Anyone have any pointers to possible suppliers.
There are any number of suppliers who can supply countersunk type washers to fit to a flat surface, but these fit into a cup in the rear of the seat, so are simply formed flat washers.
At a push I could make up jig to form them myself, but prefer to buy them if possible.
