Some more pics.

Pic 1: Top (ground plane) side of the MK2 built PCB.
Pic 2: MK2 100kHz 5mV p-p input, 700mV output.
Pic 3: MK2 1 MHz 5mV p-p input, 300mV output.
Pic 4: MK2 5 MHz 5mV p-p input, 200 mV output.
Pic 5: MK2 10 MHz 50mV p-p input, 200 mV output.

As I said at the outset, at lower frequencies the amplifier works well, but performance falls off sharply beyond 10 MHz, and by 15 MHz, there is no gain. Any thought on how I might be able to improve the HF performance would be appreciated. Just a little homebrew distraction from other things - not having a buffer amplifier hasn't left a gap in my life, but it's been an interesting little project, (for me, at any rate).
