The Waterworth Story

The bent of young Waterworth was perhaps revealed by his acquisition of membership to the Royal Society of Tasmania at the age of 17 – at whose meetings and lectures were discussed such wide-ranging and improving topics as horticulture, practical and adapted science, history, philosophy and psychology. His 1990 obituary cited gardening as his primary private passion.

Projector Model Timeline

Earlier models? with black noses marked ‘Waterworth Hobart’

Model A / B / C / H: all-silver lenses marked ‘WATERWORTH-HOBART’ and ‘X inch’. Red W circular logo.

Later models with silver barrels / black noses, some marked ‘Lyra’, ‘Rigel’, ‘Antares’

Enlarger Lenses

At least one 50/3.5 – likely derived from Elmar Tessar

Projector Lenses

The 1962 catalogue indicates the production of Model A, C and H 35mm slide and film projectors, increasing in price from £36 to £76. Evidently the range was recomputed and upgraded from the models shown in the surviving 1956 catalogue, which are uniformly slower. The 4-inch f2.6 model stands out as by far the most expensive of the 3-6 inch variants, which likely indicates it was a more complex construction: perhaps a Tessar unlike its Petzval siblings.

Process Lenses

From 9-48″ in focal length

Taking Lenses and Other Optics

Centaur 50/3.5 – likely derived from Elmar Tessar
