K1 Garratt Project (4) - Water tank prototype...

 Knocked up a cardboard prototype of the end water tanks...

clearance check round R1 curves - front 

clearance check round R1 curves - back

the back tank will have a more than prototypical gap between it and the cab. Part of the tank also served as a coal bunker and fitted into the back part of the cab - I will probably have a coal bunker on the top part of the rear of cab which will overhang the tank.
