A day demonstrating at the Swindon model ex today has seen some more progress on 37607.  The air horns have now been removed and the recesses filled (with the horns mounted onto 37612). 
 

the flint grey was repainted to the deeper depth (as was the black on the ends).
 

 An Extreme Etchings roof grill was glued into place Before touching up the roof paint and adding a start to the roof weathering.  Next job will be adding the cantrail stripe.  
 

then I will need the horn grills and transfers to finish off.

i also made a start on weathering 37521
