Here is a well preserved Falke mod 50 which has made its way from Germany to New Zealand, via South Africa where it was first bought.
It has a tangent rear sight similar to the superior mod 60 one, which must be either a retrospective upgrade or a factory improvement. (The usual mod 50 sight is a plain sprung leaf with thumbwheel adjuster).
With many thanks to Sean for these pics.
Falke Modell-50 - With straight stock.
With thanks as ever to Frank for these pics. It is certainly unusual in having a straight hand "English" stock. Frank says it shows no sign of having been modified by an owner, although it has been refinished.
Of course the original pistol grip may just have been expertly removed, although you have to wonder why anyone would do that?! Or perhaps it was an experimental design by the factory? We may never know, unless several more turn up - suggesting it's a rare variation...
Falke Modell-50 Spezial.
I spotted this on eGun recently. It looks like a very nice condition mod 50 but also has a fancy walnut stock with raised cheekpiece, chequered pistol grip, grip cap and buttplate. It also has "SPEZIAL" stamped in the barrel near the breach.
Now whether this was a true factory special or a retrospective 'upgrade' by a fond owner, I'm not certain. From these pics the buttplate does seem to be shaped like on the Falke mod 80 (or based closely on an original), but I suppose this could be a retrofit. It's hard to see whether the grip cap is also similar to a mod 80's. The stock does seem to closely match the mod 50's original standard beech stock. In short, the jury's out, but if it's a modern invented 'spezial', it's been very well done indeed.
