Two types of grease guns were used for the 250 series cars. The type with the lathe turned handle was appropriate for the inside plug 250s and most of the earlier cars. The very early cars probably used something similar, but perhaps from a different manufacturer. The late, outside plug 250s and other later cars used the grease gun with the flat, cast handles. Late Grease Gun for 250s and later cars with the flat, cast handle.
