I wish I had a couple of old Kelly's kicking around in the shed.
Just clean 'em up with a cup brush on an angle grinder and take your time to file them sharp. The old True Temper Kelly will be quite hard. You'll want a fresh file for that job. I bet you'll find them to be at least the equals of your new Council - maybe even better.
And if you have questions - ask. The guys around here have sure taught me plenty. They're very helpful.
