Yes, that size matches Ron Groen.
Could be 1983, because he was also in Gazelle's amateur team. Then it was resprayed later, when he joined the Skala team.
Gazelle frame numbers are hard to match with a calander year. There's no direct link between frame number and year.
They just numbered the BB-shells before the frames were produced. The numbering was simply ascending from 0, 1, 2, ... 328xxxx, ect...
They had some books to write the serial numbers they used on which date, when putting the numbers into the bb-shells.
So you where there at the time! Great information, thank you.
