Thanks to everyone for your continuous interest and nice comments.
Well, with official end of Heavy Hitters GB only a few days away, I'm forced to face the fact that this model won't be finished by that time. Considering slow pace of this build from the beginning I'm not all that surprised. As mentioned before cold workshop and lack of spare time are the main reasons for this.
Off course I will continue the work on this model and finish it eventually, but don't want to rush it now to meet the deadline and ruin the model in the process. Keep checking this thread from time to time as I'll continue to post photos of further progress of this build.
