I got one just recently in .22 short.
Dosent say any model number, just Browning, made in Belgium, .22 short smokeless. Excellent condition, has the tube mag that pulls out of the butt, but the bullets are fed from the top in a hole in the stock just behind the receiver. I call it the dolphin, cause it looks like a blow-hole. The whole thing when taken down would fit in a standard briefcase with a lot of room to spare.
