I received this item after a previous simple operational check. Please note that I have not performed any operational checks myself. Only those who understand this are welcome to purchase. The carrier has some yellowing. Everything in the images is included. Please refrain from purchasing if you are sensitive to such issues. This item is also listed on other sites. In the event of simultaneous purchases, priority will be given to the first buyer. Please understand that we may have to decline your purchase in such cases.
