I have just acquired a Diana model G79 rifle which is missing its front sight; I have placed an ad requesting one in 'wanted' forum but think this is more likely the best place to find one although the rifle is probably too new (1974) to be collectable.
From the Chambers site it appears to be a ramp-style with a blade and is fixed to muzzle with a 4BA screw; there is a tapped hole about 3/4" from muzzle on my rifle to which presumably the sight is attached. Chambers do not have one in at the moment and nor are they likely to soon so if anyone has one lying around or is breaking an incomplete/damaged G79 for spares them please PM me and I will buy it.
However, failing that, if anyone has a dimensioned sketch/drawing of the sight they could send me then I may be able to make one. Thanks for looking.
