engine is canadian built 24 stud unit and was last serviced in 1945 so methinks it may be an earlier one.
the mains and big ends were on 010 thou and the bore is 030 oversize using a three ring piston.
Lynn i will get some close ups. it is not the pin where the hole is mate, that is bit is ok
its up one side and has rotted through i could weld it up or tidy the mess into a nice hole for further drainage.....will most likely weld it though.
i think i managed to reveal bits of the original paint which i can only describe as a very dark grey...may not be original but it was like a hard enamel and there was nothing else under it ?
