Can anyone tell me my Sunn Amp's Model number?

[NewZealander]

I bought my Sunn amp in Boston in the 80's before I moved to New Zealand.  The model plate fell off years ago.  I kept it in a safe place, but I can't find that safe place now that I need it.  The amp is called a Session Man and is similar I'd say to a Fender Twin Reverb.  It has been an excellent amp, but it needs a bit of service and I would like to get a schematic off the Sunn Support site, but can't do it without a model number.  Can anyone help me out here?   (If you can, you get free accommodation in our guest house just outside of Christchurch NZ - seriously.)

I've never heard of a Session Man. Photos might help.
