No, David, never used him to date - what's the speciality ?
SNGB have them as BD86331 here, and have confirmed the 5/8" throat :

These will
probably work but are clunkier than the originals at 15mm x 30mm instead of 11.2mm x 24mm, and they are of the U-type instead of the J type, AND they don't self-locate.
Bosco have them here, SNU1561, 5/8" throat confirmed, to suit #8 screws, and the sizes are better ; it is still a "U" type and not a "J" type but, critically, it does
appear to have the indent that makes it self-locating :

I'll order some and find out. And have contacted Richard Smith.
