Something old and something new, a couple of Soviet acquisitions from the Ilyushin stables. The first one has been on eBay for quite some time billed as a Li-2 but in fact is what I believe to be a Il-12, this being one of Ilyushin’s first passenger airliners. The second one is a Il-86 one of the last airliners Ilyushin built the Il-96 superceeding this type.

A ridiculously expensive Il-86 yoke on eBay at the moment:

For those of you who like Soviet cold war aircraft this is a rarely seen item on the market although a tad expensive. It’s a Myasishchev M4 Altant control yoke:

The existence and preservation of most Russian yokes is due to the fact that they were presented to military Pilots on retirement, quite often they were jazzed up commonly with a clock wedged into the yoke hub and bits and bobs dangling off the wheel like a Christmas tree. The removal of the clock, compass and lowering of the price would make this quite a nice acquisition to ones collection. I would be asking for further photos around the hub area to make sure it wasn’t stressed or fractured through the insertion of the clock.

Is there any update on the fate of Safdarjang? . I remember some years back driving through a highway in Delhi and coming across this Art Deco airfield. Without knowing anything further sounds like it may become like Croydon airport, just a building in the middle of an industrial estate.

A couple of military yokes on eBay at the moment:

Martyn,
As you are probably aware the caps are generally more elusive than the control wheels themselves, A discussion on yoke hub caps was covered on this thread some months back. Congratulations on the acquisition of the VC-10 yoke at cockpitfest, a good find. A few months back three to four examples of VC10 yokes appeared on eBay all with upper columns minus hub cap and PTT switches. They didn’t last long all going within hours or even minutes on ‘buy it now’. Perhaps yours was originally one of these ? Did the seller have any history to your yoke such as the aircraft it was removed from? There was a chap on eBay a while back selling replica Vickers VC10 hub caps, I haven’t seen him advertise for a while although I did notice that he had a stall at Bruntingthorpe last year and was selling these replicas.
