I love the old .22s. I just spent a cold, but satisfying, time at the range today sighting in the old Marlin 39 I bought a year ago. I had the full octagonal barrel relined as the original bore was shot out(!). After fixing a feed issue caused by a shrinking fore end, it functioned flawlessly. So far it seems to prefer CCI standard velocity ammo, but there's a lot more to test now that it has a Marble tang sight to help things along.
