P Class 0-6-0 tank - Or something for Kingston Wharf

[The Bigbee Line]

Good afternoon,

After building a K's Terrier in 4mm in the 1970's, I have made that leap and purchased another whitemetal loco kit.  A Roxey Mouldings P class with etched chassis and motor mount, with 40-1 gears.

Any constructive hints and or tips would be appreciated.  Soldering will be my desired medium for construction.

Thanks and regards

Ernie Puddick
