Hi Bill, Richard, Duncan
Bill,
Yes, you are probably correct , when I opened the pic in photo editor and magnified it, the intact side looks
1 piece, in A cylinders I have seen relined the liner fits inside the original cast piece (spigot??) below the base line
and does not replace the original, as in Duncans,
They are just a push fit at the bottom so as not to burst apart the thin piece of the original barrel
(I hope I'm explaining this ok???)
Richard,
yes, I can see a machining mark on the liner, this is common enough when fitting liners from the top
it gives a lead in and in some cases its also a stop to prevent the liner dropping down, jacket will have a corrisponding step machined
Duncan,
Thick flange is near enough 1/2 inch,
Regards
John O R
