    Re: Need Grubb Lens Expertise

    I have prepared an updated version of my Grubb and Parsons article, using Grubb lenses owned by myself and Paul (pgk). It will appear in the magazine of the Photographic Collectors Club of Great Britain (PCCGB), Photographica World. I will post something here when the article is published.

    Re: Need Grubb Lens Expertise

    Thanks Paul for all the work involved in this. I am the proud 'new owner' of D lens No 2591 (joining 509 and 3631 in my collection - see attached photo) and which came marked with f stop 14.4 plus 3 washer stops marked f 18, 24 and 72. As you have already pointed out, these markings would date from a later period than the 1860s when the lens was manufactured as the f stop system had not been developed by then. There seems to be a pattern emerging from these studies pointing to most of the production being concentrated in the 10 year period from the mid 1850s to the mid 1860s when the Grubbs (Thomas and son Howard) seem to have decided to concentrate more on telescopes. My article on Grubb for the Photographica World magazine of the PCCGB should appear in the not too distant future. I am meeting the editor of the magazine at Photographica Camera Fair in London on 19th May and I believe that based on Paul's researches (with relatively tiny inputs from myself) there may be more than enough for another article before long. I am also hoping to photograph the Grubb workshops, homes and graves using my smallest Grubb lens (an A x) on a modern digital camera. I live only a few miles away from where the lens was manufactured over 150 years ago.

    Re: Need Grubb Lens Expertise

    I just starting reading this thread and was interested to see in the ad posted in #38 the comments from Samuel Bourne. I have several images by Bourne and all I can say is that if any of them were taken with a Grubb lens that it was one heck of a nice lens!

    Re: Need Grubb Lens Expertise

    Post #38 is an add which starts by saying that every Aplanatic lens has written on the concave surface "Grubb Patent xxxx".

    Lens with brass engraving 2215 - a simplified stereo aplanatic - actually has the aplanatic lens cell from it's stereo twin 2214!

    Re: Need Grubb Lens Expertise

    2915 has element 2914 installed! I've read the advert several times without twigging that it said that each lens was numbered on the glass!!! The list will be updated if I can get serial numbers out of several museums - some lenses are in long term storage unfortunately.

    Re: Need Grubb Lens Expertise

    All 3 of my Grubb lenses have the engraving and so far I can confirm that 509 has that number engraved along with 'Grubb Patent'. I need a stronger loupe to confirm the other two, but they both have an engraving; very faint on 2591. Will confirm details here when I have them.

    As well as Bourne and Thomas Grubb himself, there are photos by Carleton Watkins (Yosemite) and Francis Bedford (Middle East Tour by Prince of Wales) where a Grubb lens was used for some of the photographs taken.

    Re: Need Grubb Lens Expertise

    A Print was sold at Christies which was described as :

    Francis Bedford - 'Water Gate Raglan Castle', 1850s
    Albumen print, 91⁄2 x 111⁄2 in., mounted on card, signed, titled and inscribed This specimen for Ldy Rosses kind acceptance. lens 15 inches, focus stop 5/8 inch - and Mr. Grubb's 3 inch lens. medium stop. in pencil on mount.

    Which I suppose goes to prove that well known photographers have always tried to use the best equipment available and have always been interested in the equipment used, although in this case I suspect that the Irish connections were also of interest, hence the inscription. The lens referred to would have been a Grubb 'C' Aplanatic (15" focal length & 3" diameter.).

    Re: Need Grubb Lens Expertise

    Lady Rosse was presumably Mary Rosse the wife of William Parsons the Earl of Rosse and famous astronomer who was helped by Thomas Grubb in respect of the castings for his giant telescope at Birr. Mary was an accomplished photographer and was also the mother of Sir Charles Parsons, the inventor of the Steam Turbine and also the man who saved the Grubb firm when it ran out of steam (pardon the pun) in the 1920s. The result was the firm Sir Howard Grubb, Parsons and Co Ltd which continued to manufacture telescopes and other optical devices until 1985.

    Re: Need Grubb Lens Expertise

    I have a teeny weeny problem with 552!
    Morley apparently engraved his name/address and reference number on both new and secondhand items sold from his establishment. This is proved because lenses exist which have the usual Morley data, but two Morley "serial numbers". The second one with quite a lot higher number. This could mean that Morley sold the lens from new, and then secondhand later to a new owner. Or sold it twice second-hand. So the Morley address doesn't always show the date of production!
