One of the best I have found is Gloucester Councils web site. These are the ones I have so far found.

The chassis numbers with an "X" in them have a digit missing, these vehicles date from 1952 right up 1960, covering the J, JB and 101 versions, I would think that there were many other J types sold in Gloucestershire in the twelve year production run of the J type, maybe other records will be added over time.
Do check out your local council site, you never know what might be lurking on there.
