White Brothers RC.8 Air Suspension Forks
(not RC80 but almost no difference)

Specifically for 20" wheel, very rare! 
Originally designed for recumbent bicycles but I ran it on my 20" trials frame and it was amazing.  It's a bit long to put on a BMX.  It could go on some of those 20" dog sled/cart things.

This is a 'top quality' air suspension fork from a manufacturer of quality mountain bike and motocross forks.  They're up there with some the top mountain bike fork manufacturers.  No similarity to cheap child's bike forks.

Has V-Brake and IS Disc Mount.
Quick Release dropouts.

Black lowers + silver bridge, crown etc, same as pictured.
(unlike RC80 all black)

80 mm travel.

Air shock.

Light but strong, actual measured weight 1.4 kg 

Steerer tube 260 mm, never cut down.   1 1/8th inch diameter.

I still have the original box and documentation.

Used with only very minor scuff, scratch, still very nice looking.  No scratches or marks to stanchions.  Needs a bit of a re-grease but in good condition.

Currently retailing at £575
