OMNIBUS 1922-1991 This type was first issued in 1922.
Historically, these plates were used on buses, taxis, livery vehicles and rental cars.
Starting in the 1970's, when unique livery plates were issued, they are now only used on buses and taxis.

I am not sure when or if this changed before 1960.

It is doubtful if the 1957/58 plates followed the same prefixes as the previous issues.
It seems more likely that they started at some point in the high "O" series (OX or OY, maybe?) and worked their way up to O/Z 999.

1960Paul Kovalski

In late 1959 or early 1960, O/Z 999 was reached, and a new 4-digit series started at O/A 1000.
