Is this one of the old style buttonholers you put the cams in the bottom or one of the newer ones? A part number on the bottom might give you a hint or a patent number you can look up at the US patent and trademark website.

If it says high shank, you could probably use it with any high-shank machine. Some White's are low shank, some are high shank.

Look in the booklet, somewhere in there is a printing date which would tell you approximately what year machine it was made for and possibly what model White it works on.

I guess this is the old style with the cams. On the box there is a sticker which says part no 50623. Then on the back of the book it says "printed in Japan part no 69046" and then way over in the corner "7/85". There doesn't seem to be a number on the buttonholer itself. I just wondered about it. My machine is a Singer but perhaps someone has a White and could use it. I only paid $5 for it.

Try it on your machine,maybe you'll be lucky and it will fit,especially if you have a high shank machine,and you need a buttonholer.They also sell adapters to change your machine shank from high to low i believe it is.I've seen them in Sewing with Nancy catalogs.

The book was printed in 1985 which means the buttonholer is for any machine 1985 or later.

It might be worth a shot to try it on your machine to see if it works.

There is a definite trick to it...have one for my Singer 6235.

I used the settings from my old Kenmore, setting the length between 1-2 and the width between 1-2. Forget using the automatic buttonholer setup or knob. This operates its little ticka ticka tacka self around and you turn the knob to ratchet around to make sure you have everything lined up. Then go for it for a test buttonhole and if that's good do the rest of them and ratchet around each time so you know everything is lined up. You also have to drop or cover the feed dogs.

I seldom reinforce a suggestion,,,,,,but experience tells me tooooooooooo. Have fun....oh so nice buttonholes....
FEED DOGS A MUST DROP OR COVER!
