The following excellent walkaround has been submitted by David of Falcon's Messerschmitt Hangar... he's no stranger to the 109 himself, and has a host of historical photos on his site.  For this series, though, he's gone all-out on the rebuilt aircraft at Hanover-Laatzen.  The quality of this restoration (reconstruction may be a more accurate word; much of this aircraft is new-build) is quite good, but the paint scheme chosen is, well, "unusual".
