personally, I'd suggest that folk who have managed over 1000 posts don't deserve to be treated gently or with sympathy
Nice celery, though to be truthful such things aren't easy to date accurately - why didn't you buy something with a lozenge cat?
The almost dead pan cylinder shape is unusual - often there is some degree of graduation to the body shape, albeit tapering only slightly perhaps, and I don't recall seeing this virtually uniform cylinder shape before.
The cutting appears simplistic, and lacks any contrived or complex design - we're not seeing a C19 decoration showing their passion for ferny pteridomania, but you see how cleverly the cutter has used the wheel at an angle to create petals in this stylized flower head.
I don't do fridge photography - I followed Dirk's (I think it was Dirk) suggestions of buying some whiteish opaque acrylic - bend to shape using a heat gun - and then try underlighting to illuminate the subject - it's a way of avoiding bright glare, and tends to diffuse the light. Needs a bit of practise but generally works o.k.
I had a feeling that Dirks instructions had been saved somewhere - will try and locate.
The colour of this one is good at indicating the piece has some age, likewise the wear suggests it was made by Ravenscroft.
Honestly, I really don't know what to think - I've had acres of celeries over the years, some moulded, others cut - I think I now have only one.
Both the shape and cutting, on this one, worry me when trying to date this in line with your suggestion of early Victorian - and looking in Silber & Fleming I'm not seeing this style of cutting or body shape. Am afraid I'm unable to go with your date line, and though I can't support my suggestion, feel that this one is more likely to be late Victorian or first quarter C20. Sorry.
However, if you can support your earlier dating with some examples or some other indication, then will eat my words.
Your glass might possibly be Continental - we so often unconsciously assume our pieces originate in the U.K.
Apparently, the gadget mark disappeared c. 1900 - Wilkinson says it was superseded by the use of asbestos string to hold the glass, thus avoiding permanent marks, as had been the case with the gadget.
You should buy Wilkinson, despite Keith's comments, it's a worthwhile book for the few quid it costs.
