Yes, the school dentist in the 40's was certainly there, a yellow card for extractions or a green one for fillings! What did you get ?

It looks to me as though a survey was underway and the man kneeling,the 'Flagman' standing between the tracks,the two men to the right of tram 177,one with theodolite legs over shoulder plus the man bending (seemingly on the end of the trolley of the foreground tram!) are the survey team. Possibly in connection with the Leopold Street connection mentioned by madannie77. Was there a rehearsal going on for a Royal visit or something?

Could the word be 'Union' ?

Built in the second half of the 1960's .... around '65 to '68. Don't know the date it closed.

The Austin Sheerline Ambulance, there's a short interesting thread here.....https://www.sheffieldforum.co.uk/showthread.php?t=620137

If this 1938 is accurate then the original photo must have been taken later as the shop units below C&A Modes have been completed and can be identified by name on their shop fronts. Here shop-fitting needs to be completed so maybe it is 1939 for the original photo, any later would have meant wartime white painted buffer beams on the trams. How fast did shop fitters work before WW2 ?

For one horrible moment, when I first saw this, another Yorkshire club came to mind! In '66' I watched the Final on TV (b&w of course) in between dealing with voters at a Polling Station in rural Yorkshire; didn't close until 10 pm! Wasn't the alternative in those earlier days of rationing (40's/50's) a white shirt with Black shorts?. Seems to me that all sports these days are competing to see who can produce the most colourful "pyjamas", it keeps the clothing trade going

Looking for a date clue though the motor vehicles don't help much. What does seem unusual are the small figures on the front of the Standard Tram, new around 1930, as the much larger colourful style was the norm on this batch. Appears to be No 63 which was involved in an accident with Brush car No 430 in April 1933 near Firth Park. If that had been the damaged end it could have been repaired closer to the time that the mainly cream livery started to appear (1935), hence the small style. There are a few photos taken in 1938 on picturesheffield from different angles which seem to compare with this lightly trafficked scene.

What happened to the Blue and White stripes and Black shorts?

The through route from Crookes to Darnall was introduced in January 1903, there is a smaller cropped copy of this picture in C C Hall's 'Sheffield Transport'. It does confirm it as tram 175 which seems to have remained in service until 1930. I think the tram 490 picture is 1952 or later as Zebra crossings were only just becoming into operation.

The dictionary defines 'Microscopy; the study, design and manufacture of microscopes also investigation by use of a microscope'. The advertiser S C Sharp would appear to be a Microscopist's Technician as his field seems to be a supplier of 'accessories'. There is a GCSE in Microscopy,a Royal Society, the Journal of Microscopy celebrated its 175th anniversary in 2016, whilst the 2017 Nobel Prize for Chemistry was won by two Microscopy authors (Franks and Henderson) for their research. Still plenty going on around the world in this field which I, for one, wasn't aware of ! Thanks for posting it boginspro.

Does this help? http://www.microscopy-uk.org.uk/mag/artsep10/bs-jtnorman.html

The Fletchers' van appears to have a 1952 number plate.

A bit more nostalgia in £-s-d .

Picture Sheffield gives date as 22 July 1961 ( spot on boginspro!) which was a Saturday. The AEC Regent III - VWJ 541 was one of nine Roe bodied vehicles out of 85 AEC's delivered in 1956/57 for tram replacement services, seen here on Route 24 to Tinsley. Used to love the smell of Ground coffee which drifted out of Davy's.
