An early morning treat for you, with a sensational set of images, shared last night by a Twitter pal who wishes to remain anonymous.

Dubrien House, at 196 Clyde Street, home to Scottish Studios and Engravers Ltd. (Picture: John R Hume)The entry to the building - possibly 1930s/40sThey were presumably considered ‘arty’ given the angle and cropping. I never saw the building although I was told it was in a poor state of repair towards the end of its days. Looks okay in these pics though.There are a lot of inside shots. Years ago someone told me all the various processes and even named a few people in the pictures, but I can’t remember now, so I’ll take a guess at some of the departments.  I think this is the office/admin/saleThe photography department was well known and well respected. Product shots were needed for advertising and a lot of people travelled from as far as London to have their graduation photos or portrait photos taken there.Another photography studio setup. Looks more like a product shot here.Think this is an art departmentI know these are the old John Littlejohn litho cameras used to get the artwork onto film - because I used one of these old behemoths as part of my first year as an apprentice, lol. Thankfully it was *slightly* modernised, but not by much.I *think* this might have been platemaking. Either litho plates or magnesium/zinc or copper blocks. Looks like offcuts in the basket. Not sure tbhThink this might have been what passed for colour planning/assembly back in the day. The windows are masked out to stop daylight affecting things. Looks like a carpet displayed in the middle so it could just be another artwork department (?)Pretty sure this is routing/retouching/engraving and mounting of printing blocks onto wood. Looks like a big foot operated guillotine bot left and lots of hammers and metal work tools around. Could even be two vario-klishographs in the far corner! I knowThis is probably the proofing department. Looks like the old roller press used to take a b/w test print from the blocks. Big heavy bugger! Can also see the dumb waitor on the left in the middle that was used to send stuff and save legs up and down betweenArty, night-time shot.Hard at work, on that month's copy of Needlewoman magazineThe August 1937 copy of Needlewoman, with the same masthead, which would suggest the pics are more 1930s, than 1940sA 1970s advert for the business

He says: "I rescued a ringbound promotional book of 12 b/w photographs of Scottish Studios and Engravers Ltd., when it stood at 196 Clyde Street, beside St Andrew's Cathedral. The site is now home to the Archdiocese offices, just to the west of the Cathedral."

Doing a wee bit of digging, it turns out the building was called Dubrien House, and, remarkably, the company, established in 1929, seems to still be in business.

Being one of the UK's top studios, they obviously didn't shirk when it came to their own publicity shots - these images look as if they come straight from a Hollywood film noir - absolutely stunning.

Bunnet doffed to our pal, first for saving the pics for posterity, and, secondly, for sharing them with us.

I've also let our friend, a former printer, add his own captions.
