When I was a kid my most accurate and easy to live with air-rifle was an old .177 35E which shot tiny groups with H&N Match. RWS Meisterkugeln, H&N Match were the only good pellets back then.
The extra long barrel made it a bit easier to cock and I loved the hogs-back and the long slender pistol grip on the old style Export stock.
I’ve got the parts to make one up including a long 22” barrel and a glided piston but not had time to do it yet…
With that long sight base they’re great for open sight shooting. The leather washer was perhaps inefficient although would last forever, otherwise I don’t know why they attract derision which seems to be simply on its looks. They handle far better than the 95/98 family and aren’t as heavy and overkill as the 80. With the nylon washer and the 30mm compression chamber they’re not as efficient as a 99 or 77 in turning spring energy into muzzle energy but they’re ok. No long slot in the fore-end and a good centre of gravity, they are overlooked simply because they are ‘an old design’. But nearly every springer is.. HW got this one right first time.
If you like the 55 and the 30 you’ll like the 35 Export, it’s a piece of class design and engineering.
