I have 3 of these locomotives and they are copies of the LGB Cooke moguls. Ive taken apart these locomotives a lot so I can help you. To take apart the frame (the boiler and cab have to be removed first) first remove the cowcatcher, on the left hand side of the locomotive are where the screws for the frame are. The first one is located behind the cylinder and the second one is behind the last drive wheel so carefully remove the drive wheel to get to the screw, The last one is the coupler on the back of the locomotive. If it doesn't come apart remove the left hand cylinder,drive rods and wheels.
