I'm one of the silent majority(?) who has followed this thread from the beginning and collected some of the GBL models. Only now have I joined the forum so that I can show you my own work motorising and detailing one of the earlier releases since some of the regular contributors here have urged us to do this.
First I have to say how much I appreciate your contributions to this topic, either with your modelling tips, historical information or sources of modelling materials. It has helped me very much in my endeavours.
The model I decided to upgrade has not received much publicity here. In fact, I believe there has only been one other posting showing an upgrade. (Back on Page 64 by darrel).
OK, to stop beating about the bush it is the Southern Battle of Britain. I think it is fair to say the raw GBL model received more criticism than praise here and I'm reminded of The Weathering Man's review "GBL release is really a total non-starter due to distorted dimensions that totally ruin, in particular but not only, the frontal aspect of the locomotive and will be next to impossible to correct".
Well, after studying the obvious faults I found the front end was much easier than expected to remodel and get very close to the correct dimensions, providing we choose to model a locomotive that does not have the lower side valance.
The entire story of 'how I did it' is published on my Blog (the other blogging service). Not sure if I can give a link here but I dare say you will find it.
The GBL BoB loco was re-liveried as BR(S) West Country 34040 Crewkerne, early crest and fitted with a Hornby motorised chassis.
'Why I did it' is interesting because my first motivation was cost (apart from the fact I am an avid BR(S) modeller). I could not resist the favourable price of the GBL offering believing motorising it would be cheaper than a r.t.r. model. Overall, the cost has been a bit below the average price of a second hand r.t.r. Considering the work and time required for conversion, it cannot be a recommended approach for casual modellers. But, what price can you put on the creative process and sheer pleasure of turning a second rate model into something to be proud of?
Here it is.
