In one of the pictures of the horse drawn fire engine similar to the one that I saw in one of the The Return of Sherlock Holmes episodes namely "The Adventure of the Norwood Builder" indicated the year 1905 in the old photograph with Koch Bros company building at the background. This seems to be rather improbable (in Holmes' unique voice) since Koch Bros company founder will only be five years old at the time according to Wikipedia, unless Koch senior has already had a business before his son or it's totally different company altogether. Fun facts, this particular episode was based on the short story publication around the same time as indicated in the old photograph or 1903 to be exact.
