Bowman 49 Ketch

Hello
I am a very happy and proud owner of a Bowman 49 ketch
My vessel was originally registered number 390558 Dragut Rais 21 in 1981 Jersey
I have Holman and Pye drawings for her, drawn 29/06/79, Design 157
My understanding is she was built by The John King Shipyard, King Street, Emsworth, Hampshire P010 7AX
Her name appears to have become “Tetonia” and she was sold in San Deigo I think in about 2010
I purchased her in New Zealand in 2015 and she was and is now called Juno Blue
Can anyone advise how many were built or have any history. I know a Jeremy Evans wrote a report about the design and the boat under a title of “The British still build great boats…BOWMAN 49…One of the best-this cruising boat can rival anything in the world”
Appreciate any news, I have seen one other Bowman 49 down under but she was a sloop not a ketch.
