A gap in my records then I have:
1993/94 (the Mansfield and Nottingham league was renamed East Midlands League; around this time Clowne joined the Yorkshire League and Garibaldi dropped down)
League: 1st Nottingham Crusaders, 2nd Garibaldi, 3rd Peterborough, 4th Leicester, 5th Northampton Knights, 6th Bulwell, 7th Shirebrook, 8th Derby City (Moorlands YOI expelled for ill discipline)
Conference: Bulwell A, Clowne A, Telford All Blacks, Garibaldi A, Nottingham Crusaders A, Derby City A
1994/95 (the league absorbed the Mercian League which was a remnant of the MASWARLA; Garibaldi returned to the Yorkshire League and Northampton Knights joined the National Conference League for a year and a half!)
League: 1st West Midlands Police, 2nd Nottingham Crusaders, 3rd Bulwell Panthers, 4th Leicester, 5th Northampton Knights A, Peterborough
Conference: RAF Digby, Clowne A, Telford All Blacks, Derby City, Birmingham
1995/96 (Nottingham Crusaders and Bulwell joined the Yorkshire League): 1st Clowne A, 2nd Birmingham, 3rd West Midlands Police, 4th Bulwell A, 5th Derby City, 6th Garibaldi A, 7th Nottingham Crusaders A, 8th Leicester
1996/97 and 1997/98 I don't know but somewhere around that time Bulwell folded
1998/99 (also Nottingham Crusaders' last season in the Yorkshire League; Garibaldi lasted a little longer and Clowne had just folded): 1st Derby City Also rans (no particular order as I don't have one): Birmingham Bulls, Garibaldi A, Nottingham Crusaders A, Toyota-Ilkeston
The league folded after this season and then new club Nottingham Outlaws and Derby City joined the RLC where Derby City already had a team
