Hi, i have acquired 3 Lister engines & was hopping to get some help dating them & possibly the best manual to get for them.

Engine 1-----Lister 1.5HP / 750 RPM NO: 2329LD113                        compact/style
Engine 2-----Lister 1.5HP / 700 RPM NO: 4556DH2                            Light green short
Engine 3-----Lister 1.5 HP/ 700 RPM NO: 1/29430 Spec 28DHR         Dark green taller than light green

Many Thanks.
