Condition Description

The locomotive is in very near mint condition and appears to have only been lightly run. The two minor discrepancies are that the two water filler caps and chains located to the front of the loco are loose, but in a bag - with one completely missing towards the cab end. The box is in excellent condition with some shelf ware. Unfortunately, the box is missing original paperwork.

Track Test

Good Overall Runner | Please See Notes

Test Results

When the model runs in forward, it runs very smoothly. Unfortunately, the loco is occasionally shorting out on what appears to be the brake blocks or some of the brass internal detailing
