Seen this nice M88 on gun broker last week. At that time bidding was around 500.00 and figured it would sell at around 1500 to 1800. Other than having a low serial number which is common for 1891 manufactured rod bayonets I saw nothing else that would warrant the final selling price.
Al had nicer rifles that he sold for way less not too long ago. Check it out!! https://www.gunbroker.com/item/942166327
