Dear Kevin,
Not sure about the brass insert (I doubt it very much) but would be happy to
check this with a manufacturer. The first one that comes to mind is Schlegel
(which I think became Metzeler) in Coalville (Derbyshire?), who supplied
most UK manufacturers, including Land Rover.
Standard Products in Plympton may also still be making these parts, but I
think they are now called Cooper Standard.
Need to be quick before they all go bankrupt, as they are 100% automotive
parts suppliers. Sad times.
Will revert asap.
Andrew.
