What is this for?

[Handstitched]

On my Seiko machine, theres a few bits & bobs on it  that I have no idea about.And since theres no manuals available*  for my machine, I can only guess. 

Like this metal plate, just to the left of the shuttle  . It has a grub screw  in the centre that needs to be loosened , and theres nothing under it.

Each and every time I clean & oil my machine I remove it to clean under it. I'm guessing thats its for an attachment for a binder? or some other attachment?  given the 4 threaded holes , and 1 other  in the centre? 

* I have searched quite a bit for a manual . I only have a Consew 226 manual with limited info. Still searching. 

Thanks for your help

its a "quick change" slide plate for all kind of sewing devices / sewing guides. You find them more often on double needle machines than on single needle machine.

You have no manual - look for a Singer 112w139 manual - should be a quite similar machine. Or maybe JUKI LUH-521.

@Constabulary thank you so much for that   So I was pointing in the right direction.   That would be handy for repairing horse rugs , instead of manually fixing the bindings by hand. 

Yes, it is a twin needle, but never had the need to use twin needle, perhaps in the future, I have all the bits.  I should just try it anyway to see if it all  works .  This  54 year old machine has been so reliable ( touchwood), I just don't to mess with it too much . 

Thanks also about the manual    I 'll have a look around .  Theres a few knobs on top that I have yet to learn about .But  I don't dare touch them , the machine is working just fiiiine
