In 1988 the Parker "88" came in four finishes in the UK:
Corinth (longitudinal striped) 22-karat Gold plated, maroon section and button.
Corinth Silver Plated, dark green section and button.
Matte Black epoxy
Laque Maroon with dark green section and button.
In the winter of 1989 the Parker 88 Place Vendôme was also introduced in USA while the Matte Black epoxy finish was discontinued.
In 1990 the finish Laque Navy was added to the line.
In 1991 Parker raised the prices of the Parker "88" and a new Laque Black with a Black section and button was introduced, while the Laque Maroon and Laque Ivory as well as the Matte Maroon was discontinued.
In August of 1992 the complete line of Parker "88" was redesigned. The gold filled pen, trim and nib were now in 23-karat gold and all sections and plastic trim were black, as opposed to the earlier coloured sections. The high end pens were still offered and two new laque metallic designs were introduced in Maroon and Grey. Also two new matte finishes were offered, Matte Black and Matte Dark Green. While the Laque Navy and Matte Grey were discontinued.
The line-up in 1992:
Corinth 23-karat Gold plated
Corinth Silver Plated
Laque Metallic Maroon
Laque Metallic Grey
Laque Black
Laque Chinese Red
Laque Dark Green
Matte Black
Matte Navy

Rumour has it that one of the reasons for the name change was that the number "88" was at that time being used by white supremacists. In particular the neo-nazi and klansman David Lane, who was convicted in the aftermath of the murder of jewish American attorney and radio talk show host Alan Berg. Lane was sentenced to 190 years in prison, where he wrote a book in the early 1990's, "88 Precepts", in which he "provides the guidelines for securing the existence of future white children and establishing a white society". The "88" refers to the eighth letter of the alphabet, "H", and "HH" was a code for "Heil Hitler" for neo nazis.
Well, although the pen possibly could have found a niche among neo-nazis, Parker probably didn't really wish to be connected to that movement, hence the name was changed.
The line was indeed also redesigned although the features were the same. The easiest way to see the difference between the pens is that the later model had "Rialto" engraved on the body band and that the nib was engraved, while the nib of the "88" was not.

The Metallic finishes were either too expensive to manufacture or didn't sell very well, since all the Metallic designs except the Maroon were discontinued in 1995. Also the Matte Dark Green was no longer offered.

In 2007 Parker made an overhaul of the complete line and discontinued several Parker designs: Parker 100, Insignia, the old workhorse Parker "45", Dimonite, Reflex and the Rialto.
In 2008 five new models were introduced: Facet, Executive, Esprit, Contact and Slinger II, but none of these were really a replacement for the Rialto.
