The big box Electrogroom blower on wheels was mentioned in this post. We had the first one I know of in Western Canada, as my dad and I purchased it in the US after seeing one at a show. I think we paid about $100 for it, which seemed to be a pile of money to me at the time. You could blow with this blower or vacuum with it by putting the hose on the air intake on the top. I think we purchased this blower in 1963, and I still have it, and it works just fine. I have never changed a switch, or a motor and I think it still blows almost as good as the newer ones. It doesn't get used on many cattle anymore, but it sits in the barn as a back up if it is needed. Other than being bigger, it is easy to use as you do not have to bend over to turn it on and off.
You brought back many memories. I have a couple old wooden show boxes sitting in the shop yet, and one still contains a bunch of the supplies we used to use to dress cattle. There is still glycerine bars, several jars of different sticky hair gunk, two or three liners, hand shears, creolin, at least 15 of those wide nosed studded show halters. Our old feed mixing box just was thrown out last fall.I wonder how many tons of feed were mixed in it. I still have the little shovel we used to mix the feed, and it is well used as the bottom is wore off substantially. It travelled with us to hundreds of small fairs. There was no such thing as show ration in those days, so you bagged your own rolled feed and built your own. My dad even oftentimes mixed different feed mixes for different animals, depending how much weight gain, or fill they needed . I still have a pail full of horn weights somewhere here. We also used to drill a small hole threw the end of the horn and wire a small piece of logging chain across their heads to each horn. It was amazing how this would shape the horns properly.
Back in those days we cooked feed for all the show cattle especially in the fall to spring seasons. I have no idea how old our feed cooker is, as it has been here my entire life ( and that is getting to be a l-o-n-g time. I had not used it in probably 20 years, until late last summer. I plugged it in and it still worked so I started to cook barley and corn. The smell of cooked grain is something you never forget. I mixed cooked feed with our show ration, and the calves would almost knock you over when you walked into the pen with it.
I can also remember breeders dragging a bunch of nurse cows with them to the shows. The fairs usually had an old barn somewhere on the grounds where the nurse cows were kept and I can remember yearling and even an occasional two year old bull still nursing a cow. The poor old nurse cows would almost be lifted off the ground, and heaven help them if they happened to come into heat!
