1. Your listing will appear more authoritative if you spell "Krag" correctly and use "handguard" instead of "top wood".
2. An 1899 manufacture date seems questionable. Leave it out as it adds nothing to value.
3. "Wood stock good" is problematical considering the alterations and amateur sanding/finishing work.
4. Buyers probably have little interest in your personal social or sporting history.
5. There's no need to give buyers your opinion on ammunition supply.
6. ". . . bore and rifling I had checked . . ." lets buyers know more about your level of expertise than needed.

The arm in your pictures might realistically be described as "an altered US Krag carbine". The modifications to the stock and fittings reduce its value significantly compared to an unaltered example in similar condition. It's very possible that you could get more for it as parts than as a complete carbine. The rear sight, the handguard, and the barreled action might fetch good offers if sold separately without the ruined stock. (For example, not long ago I listed an 1896 carbine rear sight in average condition like yours and received several valid offers over $500.)
