[Nick Beale]

In Carl Hildebrandt's "Broken Eagles 2" (Fighter Pictorials, 1988), this machine is on the cover (in the shot posted here). On page 17 it's seen in more of a side view and the Werk Nummer is reasonably legible. I make it 152043 or maybe 132043. On the page the "dots" of the printing defeat any attempt at magnification and it comes out differently with different scanner settings but it would be quite clear on the original print, I'm sure.

Doubtless someone will have a better idea than me what Werk Nummer series are possible for this particular Bf 109 — is that a shrouded exhaust?
