[Test-Equipment] Simpson panel meter question

[John Burch]

Directed to someone with a Simpson panel meter catalog:

I have a model number 1227 Catalog Number 2520
0 - 30 DC ammeter.  

I am assuming by the weight of the meter that it is equipped 
with an internal shunt.  Am I guessing correctly?  (Dang, I
must be getting old - asking the question instead of just 
ripping the meter apart!)

Thanks in advance for any assistance.
