Congratulations!
You sound like you got a good one. And as said above, if it needs parts Graeme Forbes can get them absolutely, the wait is a while but I find that the months fade from memory after a while.
Regarding the wait, I bought my Pedersoli Mortimer Target flinter paid up in late July, went travelling, came home put in permit application in Western Australia in early November, and hope to have it by Christmas. Meanwhile, the flints (and wads for the 12G barrel) from TOTW got stopped in Customs until I explained in writing what they were all about.
