Need help identifying tooth inserts

[Pepe_Silvia]

Picked up this gang saw.  Has some missing teeth, so I'm looking for replacements.  Can anyone identify this type?

Looks like a 2½ style.  If you look on the side of the shank, it should have something stamped on it.  If its numbered, it will be like a 2½ - 9.  The last number is the gauge.  For hardwoods, they use a letter system like a B-8, or a F-9.
