And here's the progression of the "build" for this profile:
This one took less than a week, having started it on February 8th. The fantastic book "Captured Me 109s" by Jackiewicz and Wawrzynski was my primary source for this profile, supplemented by Wikipedia research and the wonderful memorial site for 3 Sqn RAAF.
Here's where it stood after the first night.

I started on this before I finished the Marseille bird since I was waiting on the Trop radiator, anyway. This is as far as I got before I was able to finish the Marseille He 100.

I was able to start again after finishing the Marseille He 100 and do a fitting of the radiator and start on the canopy armor.

Next I added the markings for the first time. I ended up disliking the red and tweaking it some. That even applied to Australia's flag on this one.

After some last minute revisions, I was happy to call it done.
I hope you all like it! Let me know if there are any questions about any stage of the process.
Cheers,
Logan
