Collectable: Daisy and Heddon VL 22 cal rifle. These rifles were manufactured for a very short time as they were deemed to be a rifle and not an air gun, and Daisy was not licensed to produce Firearms. The Daisy BB gun company's EXPERIMENTAL caseless ammo, no brass casing, nito cellulous is glued to the back of the bullet. Compressed air set off the nito cullulous. No primer, no case (brass).
