I have a MM umbrella that originally had a red/yellow cover on it. It is the type that the shaft goes under the cover to the center which holds the ribs that go out to the edges of the cover. The original cover was shot when I got it about 35 or 40 years ago & my wife made me a new one from nylon fabric. It isn't in very good shape anymore and I would like to know if new covers might be available anywhere. I can likely get my wife to make me a new one but she teaches school now & doesn't have much spare time so I would prefer to buy one if I can. Thanks in advance for any help anyone has to offer. We swap to whatever tractor we are using at that time.
