RE: Irvine Engines
Bummer, I didn't know OS had switched production to Japan for Irvine engines. I had thought they were still assembling or making them in the UK.
Oh well. I learned something new then.
In the pic of the Irvine 53 above, it says "Made in Japan" on the box.
So then the real question is that really a ABC cylinder liner in the engine or is it a ABL cylinder liner inside?
OS doesn't do ABC anymore but uses nickle plating instead of chrome. or is Irvine engines the exception?
If it is really chrome, that would be a huge plus for the Irvine engines to buy versus OS engines.
