Stella was introduced in around 1933 and lasted until around 1938.
Stella - one of the main private brand sets manufacturerd by RCNZ. It seems 1937 may have been the last year of RCNZ models, but there were sets in 1938 under the Stella name manufacturered (it seems) by Collier and Beale. Does anyone know the tie up here? Was it a new company, just a new brand, or did Stella move to C&B after RCNZ finished up building private brand sets?
