I think they all are based – more or less – on the 4444-hull (it was the first of this series):
• 5950 dark brown (with small differences: hole for the cannon, no holders, no plug-in possibilities) with a red/white deck and a white top
• 5140 dark brown with a light brown deck and a blue top
• 5009 dark brown with green deck (without top)
• 5881 dark brown with green deck (without top)
• 5901 dark red with dark brown deck (without top)
• 4444 brown with light brown deck (without top)
