Thanks for the reply. Yes I'm having difficulty finding ammo for it. As for condition, it looks like the barrel may have had work done on it. Factory stamping is missing, but looks like an attempt to engrave/scratch the model and caliber into the barrel was made. I plan on using it. Never fired a lever action before.
You'll enjoy it...more power and less recoil than a 30-30, for example and that configuration handles very nicely. I had one, a while ago.
That barrel observation sounds a little fishy though. If you cannot find out what happened there, it would be a must to ask a gunsmith to look it over. Barrel replacement, which is what it is if the factory stamping is missing, can be tricky....and what you describe does not sound like a factory job.
A gunsmith can tell you what's going on there, but you want to make sure that it is correctly installed and is safe to fire. Bad things can happen if it's not. In this case you should probably check to make sure that the barrel itself is correct and is chambered properly.
For example, most new barrels will come with an unfinished chamber so that it can be properly machined for head spacing after installation. If that has not been done, or has not been done correctly, it would be a serious problem.
You are likely in decent shape since it was in the family and if you know that your dad was using it, but it's quite common for strange things to happen when people work on guns.
You should definitely have that one checked out.
