Simonta - if memory serves, the dog incident happened at Dungannon in 1984 and yes it did try to eat a Gazelle fenestron with unfortunate consequences.
Walter was very good at ploughing as well, either with the TR (J** Ch***ler memorial trench at Aughnacloy) or with the nose door (Slack-Dick memorial trench near Middletown) and trimming trees (VDB, Cookstown).
Happy memories of 72
