Andrew told me the trolleybus had just returned from a trolleybus festival in Saltzburg, Austria, and provided an article showing 135 in attendance. Unfortunately the accompaning text is only available in german, so I have had to use Google Translate, and then translate the translation into understandable english. The following pic is taken from trolleymotion.eu and you can access the full article by clicking here.

So I did a bit more digging, hoping to find some pictorial record of 135 in action in Kaiserslauten. Alas that didn't unearth anything, and I still don't know why it has a GB plate although J reg is 1970 I believe so it's the right year. But I did find this video taken in Saltzburg at the 75th anniversary a month ago showing 135 in action. I take no responsibiity for the annoying music in the video, but the picture is of amazing quality. My thanks to the two Andrews for taking the time and effort to get in touch with information, and to my friend at Anglian for spotting 135 in the first place. Certainly made a pleasant change researching it.
