The original wooden tillers supplied with Bell kits were made of ash and 920mm long. More recently 25mm outside diameter anodised alloy tube was used instead instead of wood and is best glassed onto the head of the rudder stock.

Wicks are currently (2022) selling suitable 25mm OD anodised alloy tube with a wall thickness of 1.5mm extruded from grade 6063-T5 alloy, in 1m lengths , so just long enough for a tiller.

Tiller Extensions

3 Allen Brothers tiller extensions of different lengths
Available in different lengths, materials and styles of grip. Very much a matter of choice, and the length of the tiller can also affect your choice. If it's too long you may find it difficult to get past the parts of the mainsheet (centre or aft mainsheet), or under your arm (centre mainsheet) when tacking.
P&B recommend the Allen Brothers A4298 for a Mirror (using a Winder rudder stock), this is 762mm long. The technical drawing of these extensions on the Allen Brothers site makes it clear it does include the tiller extension joint fitting, and that the 762mm length includes the length of the joint. 
I use a (homemade) tiller extension that is 733mm long.
