[Hammarlund] SP-600 VLF Question

[k2cby]

Can you specify how and where the name "dero" appears? Is it on the original
aluminum front panel or on some sort of subsidiary panel attached to it?
Does the name "Hammarlund" appear at all?

The SP-600 was a workhorse of a receiver and it was adapted by several
contractors to specialized operations. Usually this involved an external
HFO, BFO and/or detector. In those cases, the contractor typically attached
his own name plate over the Crystal-Selector / Crystal-Trimmer section at
the upper right corner of the front panel and left the Hammarlund name plate
at the center.

Is this a "normal" SP-600 VLF? No non-standard tubes, no circuit changes, no
external HFO or BFO?
