The ALPHA R2160 was manufactured in Hamilton NZ up until last year when Alpha went into receivership...the Waikato Aeroclub was one of the launch customers and received 3 Alpha ZK-WCD, WKF, WJH (W-signifying the Waikato Aero Club, and the two following letter ar initials of significant members in the club's history).
I believe Alpha has recently been sold by the receivers and the factory at NZHN will again start turning out the R2160's.
