Well after nearly a week and a very short attention span and shorter time spent on it we have this, its the 312 Mk2
A really cruel close up the black lines are where the top and bottom of the windows will go. I am in the process of smoothing it out with fine wet and dry paper and have only done where the windows will go. I am still applying milliput in very small doses to fill in and small imperfections there are in the finish. I will leave the headcode box rough as this will need to be cut out to illuminate it. I have done the 312 first as I had the opportunity to go and measure the one at Coventry and realised that if I do the 312 first the cast it , then do a minor mod to make into a 310 then cast it , then finally cut the windows out to make them wrap around. compare it to this
the windows are a bugger to do as they are the same generic type common to both classes I decided to mess around with thin plasticard like so
Sorry it's a bit blurred and a trial fit looked like this
the buffer beam is a bit on the deep side but you get the idea. again I was still unhappy with this and decided to try and have a play with it even more. It's moving very slowly and all of the rough edges are coming off 1 by 1
