- Brand: Nikon - Model: PG-2 - Function: Focusing Stage Thank you for viewing. This item was passed down from a deceased person, and the original purchase date is unknown. I lack knowledge about the product, so detailed operational checks have not been performed. (Both the upper and lower rails moved smoothly from end to end without any significant catching.) ● There is a small oil stain on one side (last photo). Other than that, there appear to be no noticeable stains or scratches, but it is not completely free of signs of use. Please understand this before considering a purchase. ※ You can save on shipping costs by purchasing this item together with other items currently on sale. Please inquire.
