I use my original tool kit grease gun for the Model A. I like a couple brands of older American made grease guns, but I looked on ebay a few weeks ago and the only known American made pistol type grease gun I could find was a Lincoln gun, and the price is $33 with shipping. A couple years ago I bought 2 guns from Menards when they went on sale for $10 each, but they leak grease and make a mess. You can guess where they were made.
