BCAL 320 four wheel bogie..?

[JanetFlight]

Hi all....please accept my apologies if this is not the proper place, but i will kindly ask your always welcoming knowledge and explanations.

Last night i was checking this airlines auction site, when i stuck on this item »»»

https://www.airlineslides.com/listings/details/index.cfm?itemnum=1030209121

Alt View in case it goes selling (by Charly007, the OP credited as seller)

So here it is my doubt...i searched in all web last night but every site, picture, etc, this very same F-WWDA appears only with a normal two wheel boogie.

Only the 320s from Air India // Indian Al. appears like this with 4 boogie.

Even no mention at all in any historic site about it...so any help or possible explanation please..??

Tks in advance...Friendly, JF :)

The photo is of MSN 2, retained for the first 4 years of its life by Airbus and for a time painted (on one side only) in BCal colours, though of course it never entered service with them.

It's quite possible that it was used during development of the 4-wheel MLG while still painted as such.

4 wheel Boogie......is this a new dance?

Probably a phone autocorrect: they are a bane, but can be inadvertently funny.
