I'm not much of a rescriber... Most of the time, it's unnecessary, and oftentimes inacurate and/or out of scale.... As far as changing the panel lines to reflect an F vs. a G, it's only going to happen where there are lines that are either missing or are glaringly or "wrong enough" in location to warrant it... Don't need a new canopy either, just need to modify the fuselage at the bottom of the windscreen to have the clear panel..
That said though, the model itself has some nicely done recessed lines, with a neat row of rivets running alongside each one.. I'll have to study them to see if they require relocating... For 16.95, it's an out-standing kit, far beyond what I expected in a Revell kit, so I'm thinking that perhaps it's a reboxed one...
The decals are a bust though, apparently having gotten wet at least once at one or more points along its journey... But I think I can save the majority of them anyway, with a little help from Testor's Decal Bonder... The best ones on the sheet are the Hakenkruezen ( swastikas), however, Von Hammer refused to allow his aircraft to displayed with them, a sore-spot with Dicke Hermann...
But there was no arguing with the "Hammer of Hell" on that point, with his being Germany's leading Experte from WW1 (out-scoring even Von Richtofen), and being one of only two men in Germany's the Luftstreitkräfte (the Imperial German Air Service, forerunner of the Luftwaffe) to ever receive the Grand Cross of the Order of the Red Eagle, which was the Kingdom of Prussia's highest decoration, and rated above the "Blue Max", and the order was only conferred to less than fifty men from 1707 to 1918... He was decorated with it in 1918, after being knighted in Decemeber of 1918.
He wore the traditional WW1 Imperial German Air Service Pilot Badge, rather than the Luftwaffe version... However, the Nazi Luftwaffe Eagle was part of the uniform, so he was forced to bow that particular regulation... He also wore it to "identify" with his pilots and ground crewmen (who may or may not have felt the way he did about the ***)... However, I digress...
The next kit in the line of Von Hammer's aircraft are going to require another Bf109G model, then the Me 262... I haven't decided if Von Hammer went onto fly in the new Bundesluftwaffe (he's kinda gettin' up there ya know) with Hartmann or not, but an all-red F-86 would look pretty cool, I think, lol.. Then too, there's always his grandson, Leutnant Franz von Hammer... That would allow an all-red F-104, then maybe even a red Phantom(?) too, lol.. 'Course, Franz von Hammer later got in a dogfight with Batman and was shot down and killed in the crash...
Maybe I'm reading too many comic books works of pictorial fiction these days...
