I have a source which contradicts Shavrov and thus Nemecek on the PS.

My source states that Shavrov was mistaken in believing the transparent material to beRhodoid, but was in steadcellon.This may well be just confusion of trade names.

Where my source differs fundamentally is the aircraft used in the experiment. My source states that one of the AIR-4 aircraft was used. This can be easily verified if there is a photo available, as the AIR-4 aircraft had split axle undercarriage, unlike the AIR-3's single live axle.Petebutt (talk)18:25, 9 July 2011 (UTC)[reply]

• Interesting as you say it would be nice to find another source or an image to clear up if it was the 3 or 4. I have re-checked Nemecek and it says AIR-3.MilborneOne (talk)18:33, 9 July 2011 (UTC)[reply]

i KEEP FINDING THE air-4 REFERRED TOAS THE SORIGIN OF THE ps, BUT NOt many PUBLISHED SOURCEs OR PHOTO YET. sHAVROV DID A STUPENDOUS JOB BUT HE WAS HOG-TIED BY THE sOVIET SYSTEM AND HAD ACCESS TO ONLY LIMITED MATERIAL. Errors in his works are many but understandable. One published w]reference is at[1] -

I have found a photo but it is of poor quality and the u/c is barely discernible and not conclusive. Go to[2] pg.83Kozlov PS. Gunston also states that the PS was modified from an AIR-4. This is very likely for another reason, as the AIR-3 was built in 1929, so would have been a bag of nails by 1935, if it was still in one piece!Petebutt (talk)14:30, 11 July 2011 (UTC)[reply]

I would agree with the logic that the second AIR-4 would be more likely, we could change it and use Gunston as a reference.MilborneOne (talk)18:39, 11 July 2011 (UTC)[reply]

Perhaps I should have read your changes to the article first! - no problems with the changes, thanks.MilborneOne (talk)18:46, 11 July 2011 (UTC)[reply]
