Yes, thank. I also checked KMP web site.
I would buy P-47 from a distributor in Japan.
They import it from ESM(the same company as KMP imports
P-47 from) and the retracts from another company( also the
same company KMP imports the retracts from), then sell them
together in Japan like KMP does in the States.
So, I don't know if the retract is totaly the same as KMP's,
although they say the retract is a new version. They don't know
KMP's version of the retract.
ESM(KMP) P-47 sold in Japan comes with a variable speed valve
and costs about $60 higher than in US.
That is not so bad for me when the shipping cost from US is taken
into account.
