Have been looking forward to the eventual Flight Replicas Bf 109G's, while enjoying the K-4 immensely. Numerous 109's are under restoration to airworthy right now, with Daimler-Benz engines (DB601 and DB605), once thought near extinct, seemingly coming out of the woodwork in recent years for these projects.
Bf 109E-1 (C.5-88) - under restoration for Robs Lamplaugh (England) - (very early model, Spanish Civil War vet, with the "rounded" braced canopy).
Bf 109E-7 (1983) - under restoration for Air Fighter Academy (Germany).
Bf 109E-7 (2023) - under restoration for the Military Aviation Museum/Fighter Factory (U.S.).
Bf 109E-7 (3523) - at Planes of Fame/Fighter Rebuilders, pending restoration for Dan/Tom Friedkin (U.S.) - (engine already under rebuild with Mike Nixon).
Multiple Bf 109F projects under restoration in Hungary and the U.S. (there's a company in Colorado which has the remains of three or four original Bf 109F's alone, said to be under restoration).
Bf 109G-6 (410077) - at Midwest Aero Restorations, under restoration for Bruce Winter (U.S.) - (owner of the P-51 "Happy Jack's Go Buggy").
Bf 109G-6 (440738) - under restoration for Air Fighter Academy (Germany) - (very near completion).
Bf 109G-4 (converted Buchon) - under restoration for the Military Aviation Museum/Fighter Factory (U.S.) - (very near completion).
Bf 109G-12 (converted Buchon) - under rebuild/conversion for Air Fighter Academy (Germany) - (the G-12 is the two-seat trainer variant).
HA 112 Buchon - under restoration in standard configuration at Planes of Fame, Chino (U.S.).
Several other examples in private hands in various states of restoration.
Unfortunately all three of the airworthy Bf 109's in Germany (Buchon conversions) operated by EADS/Messerschmitt Stiftung are currently down for major servicing and/or repairs. The only original Bf 109 currently active is the Flying Heritage Collection's Bf 109E. The once flying Canadian-based Bf 109E, owned by the Russel Group, has been sitting hangared for several years now, available for sale (in need of a very spendy prop and possibly engine overhaul (due to the hours on them being up)). The only Buchons currently active are the two based at Duxford, England.
