The FWB's do NOT use a Giss system, they use a sledge system and is not considered truly recoilless.

What do I know? Just the mangled memories of stuff I read forty years ago, with a major hobby change in between. Lol

I am looking at buying this lefty D75. Can anyone tell me more about it? The stock looks different than the ones I've seen. I can't quite make out the year of mfg, it's 01 8X.

it is a Diana model 75S TO1
it has a Diana model 100 diopter with long sun shaded and has a 200.00 to 300.00 Iris on the Diopter that sight is a 20 click model vs the 10 click with the earlier sights
by the time this rifle came out the Model 100 diopter might have been standard vs being and option
stock has been refinished it should not be the shiny and it is Beech
this rifle and the Model 75 B TO1 were the last of the variants that were made
it is rare to find a Lefty

Thank-you Marflow, thought you might know something about this gun. The sights it is pictured with are Gehman, front and rear. The seller found the OEM front sight but hasn't located the rear yet.

Small correction.
That sight is not a Diana 100 sight, it is a Gehmann sight. A model 590 L.
The sight alone retails for 180 to 200 dollars sans the adjustable iris mounted on it.
The diopter looks like it has polarization adjustment and possibly diopter correction as well. You are looking at close to 500 dollars US for the rear sight set up.

you guys are right on the diopter and it is even better and how i screwed that up, it is embarrassing

Not at all embarrassing my friend.
First look, I thought the same as you did.
Being a lefty, I was ogling it pretty good, and the Gehmann just smacked me right in the eyeballs after a minute or two.
If the price is close to reasonable, and it comes with OEM sights, the OP should grab it up. If it comes with both sets of sights, that is an excuse to buy another 10m rifle!!

the rifle as far as i know came with a Diana model 100 diopter and the front globe would have been a double screw cap that uses 15.9mm metal inserts
now would i as a collector want the factory sights and the answer is yes BUT if you got the rifle with newer, better sights i would not be upset and or pay less
the cost of just the Gehmann pieces, front globe and rear with the iris is about what the rifle is worth give or take
does the sights make the rifle less or does the stock being refinished wrong do that
i have a 75S with a full gloss stock but i found a new factory stock for it in Germany in factory brown paper so i do know what it should look like
the bottom line is most or all of these aging rifle have had some changes but the heart and soul of the rifle cannot be changed
and this being lefthanded it is a prize
the sights can be found, inserts can be found but the upgrade that is there is just that an upgrade

I just set up a FWB Sport, I know, not a Giss system, with one of the Gehmann 590 with one of the diopter 1.5 corretion adjustments. Fantastic for my old eyes. Pricy, yes. It was almost hard to believe when I mounted it, it only took about 3 clicks of windage to get a perfect zero.Small correction.

Beautiful Diana 75S being discussed above! As an aside, note that the action - not just the stock - is well and truly left-handed, with the cocking lever and loading port cutaway on the left side. The D75 and the rare early-1960's Anschutz 220 were the only recoilless springer match rifles made that way.

Being a left handed rifle, the stock will also have a left handed cast to the butt plate assembly.
Diana carried that feature through to the Diana 100 model, though on the 100 it was accomplished with a spacer that would cast the butt pad right or left. The Model 75 should have the cast off manufactured into the butt end of the wooden stock.

It does and has a spacer that adds cant. You can remove the spacer and only have the cant of the stock, although LOP changes.
