1. Where can I get a 7 pin core for it?
2. Where can I get the correct keys for it?
Here are a few pictures of it.

Here is the pin stack... When I went to pick it I only set pins 1,2,4 and it opened. When I took it apart the #3 and 5 pins look like they are right at the sheer line.

Here is the keys I have to make some keys for it... I dont think they are good because it has the cut along the upper part of it and when cut the pins may not ride on it...????
Oh, and here is a pippen file that a locksmith gave me...

I really want to make this thing 6 or 7 pin but not if it costs an arm and leg..
