In the Rowlands/Francis/McGrath T&DR book, there's a pre-GSR pic of one of the Hunslets, a coat of arms can be just about made out on cab side sheets.
Might have been a 'one off', applied to just one loco, never came across another pic like it.
Also appeared on the cover of their 'Thro Rare West Kerry' tourist guidebook.
The 'new' T&DR (incorrectly) applied the same design to coaching stock.
