Switzerland license plate, Dealer pre-1977 (1977 to 1980), sample RQ 652577

Format, years and the law

Format
LL 999999, for example RQ 652577 (L is any letter, 9 any digit)

Only the canton code is left to read. How these pre-1977 dealer, rental and test plates were specially marked sits in repealed instruments nobody has retrieved, and by 1 January 1980 every last one had to be off the road.

The format above is broad: a registration that fits it has the right shape, which does not show that this series issued it.

Years issued
1977 to 1980. No longer issued.
Vehicle class
Dealer: trade/garage plates bound to a business, not a vehicle. Issued for car, van, truck, bus, motorcycle, and trailer.
Colours
Characters #000000 Background #FFFFFF

About this plate
What the period records is the WINDOW in which they remained lawfully on Swiss roads under the VZV's own transitional rule: from the VZV's entry into force on 1 January 1977 until the three-year exchange deadline expired on 1 January 1980.
About the format
A match says only "this string has the shape of a Swiss cantonal registration", never that it is a pre-1977 dealer plate.
