Lester wheels

[Slarsonroy]

What year were Lester mag wheels available for Guzzi? My 1976 Convert has a Lester front and spoked rear. Searching the internet, I found just one picture of a Convert with Lesters on it. Were they available in 1976?

My 77 T3 had Lesters. I prefer wires, but in the 4 years I had it, left them on. I liked the way they looked.
