If the body shell is used for all the liveries then be careful because this is a vacuum brake loco. AB/DB locos had an additional "box" on the LHS for the compressor. otherwise a great model .
Dapol has stated that they will adapt the model as they go through the ages. People wanting the more modern variants will have to wait a little longer.
The 08 shunter can be bought from many online sellers including Hattons and Tower Models. 13308 'Charlie' variant is a limited edition and can only be obtained by being a member of Dapol's collectors club.
