TYER

The design was further refined to produce the No.12 see below. This again was an aluminium fronted machine with a commutator arrangement based on the Mk.2 No.11 one albeit again simplified to aid manufacture. The use of die casting was adopted. The number 12 was available in a large number of variations for various customers. The number 12A/6 was the GWR version with the left hand switch assembly. Most machines could be fitted with hand generators and permissive working attachments. Certain number 8s and all number 11s and 12s can be fitted with token transfer magazines.
