Today after a year of thought and search I believe I may have the answer to the question "what make of floor springs were used on the Titanic." https://en.wikipedia.org/wiki/RMS_Titanic
Readers may or not may not know that the Titanic had a sister ship, the Olympus that did not sink and was decommissioned in 1935. https://en.wikipedia.org/wiki/RMS_Olympic
The interior, almost identical to the Titanic's, was auctioned off in November 1935. Some of this interior was used to build the Olympic room inside the White swan Hotel, Alnwick and can be still seen to this day.
It is from the 1935 auction catalogue that I have been able to trace the manufacturer of the floor springs sold at the auction, which were used on the Olympus and logically therefore the Titanic. Details of the lots can be found below (Especially doors and their control gear).
The answer therefore to what make of floor springs were used on the Titanic? Probably Yale and quite possibly supplied by Comyn Ching but that's another story for another time.
