I have had this one for a while and do not know its early history as I bought it for my railway used. I don't think it has been modified since leaving Wrenn and I do know a few got out in this disguise but I cannot vouch for that.
This one was in really good condition, and is a really good example of Wrenn locos.
Converted to DDC it is much better than a new Honby at twice the price.
