Piston expert required
 

I'm trying to locate a set of a particular piston for a rebuild (piston lands are broken between top and centre rings)

Piston has these marks on it

P-1919X2

BRO .025 (or possibly 8R0 .025)

82.485

And a stylised piston symbol which I think is indicating a dish depth of 8mm, and at the bottom of the symbol has 808

Anyone have any idea?

WHAT are these pistons from James? I have a set of WR pistons with alegidly 19k miles on them and a set of new unused piston rings curtesy of Stephen Pirrie who now longer has a use for them.
Kerker21 has first call on these but if he doesnt need them perhaps these are what your looking for?

I'd guess that the 82.485 is the piston size, ie it's a 2309 cc engine with standard sized bores ( bore size 82.5mm)
