I remember when.

 Whilst having a rummage in the olde shoe box I came across these photographs of this Grumman G-1159 Gulfstream II N500R c/n 12 as seen at a wet Wellington Airport in late March 1970. 

It went new to Superior Oil sometime in 1968 as N500R until moved on in late 1970.

It became N11UM followed by N154X, N115MR, N160WC. N212TJ, N794SB and finally N622RR in 2001. It was cancelled on 13-08-2013.

My notes mention it being black with a red, white and light brown fuselage stripe and silver engine cowlings.

I just thought you would like to know.
