I have the Model 43 in a .218 Bee and love the rifle. That being said, I know of some folks who have the same rifle in .22 Hornet that have had some head space issues, resulting in cracked cases near the rim. If you can shoot it, you should be able to tell. If not, ask for some recently fired brass to inspect. Also make sure the magazine works.
Otherwise, I think the price is a bit high, but if it is in good condition, you will have a nice little gun for many years to come. Also, if it is a Deluxe version (checkered stock), it will be worth more than what he is asking.
