Question about PUW 1561 escape cap jewels

[Lc130]

Hi All 

 

I'm a beginner.  The escape wheel has block shape cap jewels on either end without oil wells.  Would I place oil in the holes on the inside?

BTW, any idea why this design?

Thanks

Charlie

That sure makes oiling without cap remival easy.
