Wow, what an heirloom. Such a gorgeous piece of furniture, even leaving aside the sentimental value it would be a crime to risk scarring up that wood and it's beautiful patina with a failed picking attempt using improvised tools.
Locks like that one usually take a fairly simple key, sometimes so generic as to be able to buy a spare off the display counter at a locksmith shop. If you visit a local shop and take a copy of those pics with you and if possible some caliper dimensions of the keyway width, height and post diameter. He might be able to help you with a guess at a key. However if it's not too large, have a friend help you lift it and take it in with you then you can try the key right there to see if it'll work. If the key doesn't work, it shouldn't be any problem for a locksmith to get it open for you and either figure out from there what sort of key it needs, or even possibly replace the lock with a new keyed one. There are a few different types of locks for furniture like this and it's more than likely that if you can't get a key, a replacement lock can probably be ordered that can use the existing screw mounting holes for this lock. I understand your desire to just get it open, but you have to admit it would be a much better heirloom if you had a working key for it.
If you're determined to pick it, the picks you would use would basically be different lengths of bent, stiff wire. Being sure to round off any burrs on the tip.
Whatever happens, please follow up with us once you get it solved. We get these questions a lot but it's rare for us to ever find out what happened in the end. If you do go the locksmith route and if for some odd reason you can't get a key and need to replace the lock, remember to keep the original one just for the historical sake of that piece of your family's past.
