THE BELDING & MULL IS A VERY OLD AND ACCURATE POWDER MEASURE. UNFORTUNATELY THE ACTUAL MEASURE IS A BRASS TELESCOPING TUBE THAT ATTACHES TO THE MAIN UNIT AND OFTEN GETS LOST. I HAVE SEEN SEVERAL SOLD ON EBAY WITH THIS NECESSARY PART NOT INCLUDED. I HAVE MANUFACTURED A NICE REPLACEMENT MEASURE TUBE FOR THE BELDING & MULL TO ALLEVIATE THE PROBLEM. IT IS MADE OF SOLID BRASS TO ALLOW SAFE USAGE WITH EITHER BLACK POWDER OR SMOKELESS POWDERS. AT MAXIMUM CAPACITY, IT HOLDS APPROXIMATELY 110 GRAINS OF POWDER. GET SEVERAL AND LEAVE THEM SET FOR PET LOADS. I SHIP ABOUT 95% OF ORDERS THE SAME DAY I GET PAID, MOST BY FIRST CLASS OR PRIORITY MAIL. "Make Offer" is only if you want more than one.
