If you mean airliners, mainly Britannias (Monarch, Redcoat, etc) and Invicta Vanguards. The odd Aer Turas CL-44, Balair DC-6, BMA Viscount & F27. On the freight side CV580, Shorts 330/360.
In terms of lighter aircraft, a much wider variety ranging from Fournier RF-4s and C150s up to DH Doves and Bandits.
