These are weights used when converting Tetsudo Collection Pocket or Nostalgic Tetsudo models to N gauge. Since the running parts for N gauge conversion are for 4-axle bogies, using them on Tetsudo Collection Pocket models will leave two wheels unused. To avoid waste, I made these weights. The weights do not have holes, so please cut off the protrusions on the body side for use. 12 pieces included. N Shell Weights for Tetsudo Collection Pocket (12 pieces)
