I am trying to locate a 22u NTI cap for the Apple 1, the one with a clear greenish covering and red lettering.

Looks like a Siemens logo. See: http://www.bungartz.nl/hist-siemens-logo-halske.jpg
HI I have been looking for the last 6 months and have located nothing. I have found some yellow colored caps with red writing, but this one has eluded me since i commenced my Apple 1 project.
I have always thought they were made by Sprague or Siemens.
But the previous post would suggest almost 100% it is Siemens.
I'm sure someone has NOS lying around, but I have not been fortunate in locating these capacitors so far.
What have other NTI board builders used?
This is the closest i have seen so far, but they look too large and no longer available.
This is a typical filter cap. Are looking for true originally from 30 years ago? If so, then you have to hunt for NOS. Trying finding an old Lambda linear (non-switcher) power supply and rip it apart for a used cap.
If you are willing to put aside originality then buy any axial cap that meet the minimum value of 22mf and 25V. You can use a higher voltage cap but the size will increase. Do not use a lower voltage because you risk dielectric breakdown. This is a filter cap, so you can even go higher in value 25mf, 50mf but again size will become a problem.
