failed to deliver consistent results under Graham's leadership. The Panthers then announced that Corey Neilson had returned as head coach until the end of the 2022–23 season. Neilson had previously played with Nottingham from 2006-2013 and coached the team from 2008-2018. Name origins, logos and colours The origin of the name Panthers is uncertain. One of the most widely known theories is that the club were named for a squadron of Canadian airmen based near Nottingham during World War II. However, there is no evidence to suggest that such a squadron existed and records indicate that the name was coined before these events could have taken place. A souvenir brochure produced to mark of the opening of the Ice Stadium in April 1939 stated that the venue's new team would be known as the Nottingham Panthers. It does not, however, explain the rationale behind the name. Three games were played by teams using the name Nottingham Panthers during the winter of 1939–40 before the name was revived in 1946. During the original era the Panthers did not have a logo, instead using stylised lettering on the front of their shirts. The club's current logo was adopted in 2003 and is the fifth to be used since the Panthers were reformed. The first was used between 1980 and 1994 and was the silhouette of a Panthers' head in a red circle. The second logo, adopted in 1994, was similar to the first but used a more detailed Panthers' head. The third logo, introduced in 1998, featured a keyhole shaped like the head of a cat with a Panther reaching through it. The fourth logo was adopted following the move to the National Ice Centre and was similar to the logo of German side Augsburger Panther. The stylised lettering used during the original era was used again on special shirts made to mark the sixtieth anniversary of the club in 2006. The colours used by the original Panthers were black and white. Home shirts were black with a black and white striped lining on the shoulders. When the club reformed in 1980, the black and white colours were also revived, with a gold lining also being added to the jerseys. In 1996 red was added to the colour scheme of the shirts. In 2001–02 the club's colour scheme was changed to black and gold. Home jerseys are gold with a black lining
