This is a delicate Mule Ear Combination gun which has really nice lines.  The top barrel is rifled and about .44 caliber.  The bottom barrel is smooth bore and slightly larger in diameter.  The barrels are extremely well made and joined.  The mule ear lock functions perfectly, one hammer at a time or both at once.  The stock is walnut with brass mountings and is very sound except for a small crack above the lock, which should be easily repaired.  The gun is devoid of any markings but it does have nice architecture.  A fairly scarce American made rifle.  SOLD!!
