This popped into my inbox today but doesn't appear on The Register, although it carries a Triple M Register badge - K3 Replica built on an N Type chassis.
I also can't tell much about this car. All I know is that it had an owner in Germany in about 2013. At the end of 2006 a Mr. Kennedy from UK possibly had the chassis only, a later owner in England was Chris Cadman, who may have initiated the rebuild. Gerhard
This car was one of the last built in the style of a K3 by the late Peter Gregory, and as Gerhard notes it was owned by Chris Cadman who I believe bought the car from Gregory.
The advert states "the old FIVA (2013) card states that it was rebuilt to K3 spec in 1979." This appears to be a typing error?
