Wild-arse guesses:

1. HJ-style wiring on a purportedly pre-HJ specimen
2. Varying date codes on pots or wrong housing size for the era (can't quite make out the codes, though)
3. Extra/wrong transformer mounting hole
4. Wrong chassis - extra preamp valve position for PA head
5. Wrong chassis plating for the era?
6. Something about the head case/vynide I can't quite pin down....
7. Seller is vintageampsuk

I think we've seen this one before - that superfluous xfmr mounting hole stirs a memory......

[Dr.HI-TONE]

some good observations...

I'll let some others chime in before "grading the quiz answers"

[Dr.HI-TONE]

actually the transformer mounting hole is accurate.
The chassis is from the 9xx-early 1xxx's, this version of the Hylight era chassis was used from the 9xx's through 4xxx's

I know this era chassis intimately

The serial number doesn't make sense, but otherwise it looks very similar to DR103 s/n 1097 - HJ style wiring, same board layout with both halves of V2 used, same head box, same chassis, offset s/n plate etc. What am I missing?

not much. You are spot on. From the viewpoint that this amp is from the serial # range 1000-1100, which I am confident, the only issue is that the serial number tag must be unoriginal to the amp.

From the perspective that the amp actually is #5xx the list of problems is substantial.
