Orange Slave Amp

[pollenrocker]

I would like it if anyone could give me information on this Orange amp, here are some new pictures I took of it

The number is 326 and on the side it looks like it was made December of 1971. If anyone could tell me how much it might be worth or if you are interested that would be great too.
