  • My MacGregor G 479

    This nice piece of history arrived to me today.



    Primo condition except I cannot keep air in the dang old bladder. It can hold about a pound and then looses pressure with a slow hiss.

    I'd like eventually to get this old guy back on the platform, but as of now he is down for the count. All and any ideas appreciated.

      Ah yes a long neck MacGregor. The MacGregor Goldsmith that I recently acquired has the same bladder problem, the valve is old and doesn't close all the way at full pressure. I'm eventually going to replace it with one of the Title large latex bladders

        Is there something similar to fix-a-flat that can be used in an old bladder like this? On the one had, I understand it is a very old leaky valve and I should not waste the effort on it. On the other hand, this bag might be as old as I am, and it would be a real joy to get the thing kicking after all these years on the shelf. Know what I mean? It came in the original box, and has that old sporting goods store smell.

        p.s. Dutchman, is there any way I can figure out the year this bag was manufactured? The bag and box have the Brunswick logo along with the MacGregor name.

          Brunswick acquired MacGregor in 1958, so it's no older than 58 years old. It looks typical of the output of the late 1950's, early 1960's production. The non golf line of MacGregor (the old Goldsmith line) had ceased to be by the time that Brunswick sold MacGregor to the Wicks Corporation in 1979

            As far as the leaking valve, about the only viable thing to do is make a plug for it. I use a Q tip swab stick cut to about 3/4". I've found that it's long enough to seal the valve, and still have enough to pull it out to ocassionally re inflate the bag. The sealer that sporting goods store for fixing flat soccer balls all seem to have the warning "Do not use with balls that have bladders", so there is something in the stuff that doesn't work for our needs. Probably dissolves latex rubber as that is what a lot of valves are made of. Wouldn't affect butyl rubber

                OK, somebody say to me "way to go, Sherlock." This bag came in the original box, and a year was stamped on the bottom of the box. Duh.



                1962, an excellent year for boxing. Dutchman, you called it very close. Thanks!

                    I managed to get a little Hive brand lib balm on a needle and up into the valve. I think between that and getting a needle in an out of the valve is loosening it up and it is making a pretty good seal now.

                    My next task is to get a proper conditioner or oil on it. It's old 'roo leather, slightly abraded in a few spots, and the leather lace looks pretty delicate. I have read (and been told) mink oil and perhaps a mineral oil are good for the old 'roo leather bags. I welcome any input.

                    Thanks,

                      As far as conditioning the leather, if it's as sound as it appears, definitely go with what ventanakaz recommends, he has a lot of experience when it comes to this. I acquired a Spalding bag from him that he conditioned, and the best way to describe it is magnificent.

                        Dutchman, I think I am in luck! The MacGregor 'roo bag has held pressure for 2 days with very little loss.



                        My next step will be the ventanakaz mink oil paste and then let it rest for a few weeks. Heck, it has been in the box since '62. What is a few more weeks?

                          ...When I get a new or old new bag to me there's noway I could wait that long, My first step as always is to change out the bladder if needed and then treat the leather, I have to see how it hits and if it can hold up, Some of those old bags may look good from the outside but could be dried out in the leather it's self, So no matter how much you treat the bag it may Crack, But Kangaroo leather is very strong, I had a very old Higgins bag that I got off Ebay that looked brand new but it started cracking as soon as I started hitting on it

                            Do you ever treat the inside of the bag?

                              ventanakaz and Dutchman,

                              After a week on the standby hook, this old bag lost its pressure just sitting there. I think my efforts to re-inflate made situation worse. The valve is being a real PITA and wanting to be open more than closed.

                              I did get mink oil and slathered the bag and it looks and feels pretty good. Is there an appropriate bladder swap for this weird long neck bag?
