I remember going there in the late 1960's for the firm of Accountants I worked for to do the audit of some of the firms books that operated there. There are 3 things that I still remember. One was that I was walking down a narrow corridor and hearing a rattle in front of me. The next thing was about 6 sides of meat come flying round a corner on an overhead rail. You had to be quick and lean against the wall, otherwise you got flattened,
I remember that one day I parked my car near some buildings. At dinner time I went to my car to eat my sandwiches. Unfortunately, I had parked near a vent, and the smell from that had got into my car. It was so bad, that there was no way I could eat my food. It took days to clear the smell from my car.
I remember a man walking past me with 2 buckets full of raw tripe. It was pure black. Up to then I had often enjoyed having a plate of tripe at the stall in the Castle market. You used to buy a small plate with the "white" tripe on and then add your own salt, pepper and vinegar. Anybody else remember that stall. Also my mum used to cook tripe and onions in a milky source. We used to have this on a bed of bread and butter. I do not think I had any further tripe after seeing the raw black stuff.
There was a firm with a name I believe of Sheffield Hides, Skins and bones. I believe they had a premises in the abattoir They also collected these items from most of the butchers in the Sheffield area for recycling. Not sure what happens today.
