From pictures bumpers are installed in an inverted position. Reverse them

I understand that they are different. The problem is the same though. Pulling
a box in and out of a rack with feet or bumpers on it is a pain. They often
get “lost” early
The 58503A in the picture on leapsecond.com looks very similar to my older
34401A DVM which doesn't have separate feet. The molded plastic pieces on
both ends have those crenelations that serve the same function.

Hi
The desktop version (with handle) used the rubber “bumper” wrap around for
feet. The bumpers got pulled when they were rack mounted. The ones that got put
back on may or may not be identical to the originals. That’s a very normal part
of the surplus process. The 100% correct HP original
Much of the Malaysian Agilent gear uses this style of case with a wraparound
bumper in place of the system II feet and feet are removed when gear is rack
mounted.
One of my best surplus buys ever was a huge crate of mixed mounting hardware

Hi
If you type 58503A into Google, it will come up with a whole raft of pictures
of various angles on the device. Since none of them are from HP / Symmetricom,
any / all *could* be fakes. Logic suggests that at least 90% of them are the
real thing.

What Bob suggested is just what I did. The leapsecond photos happened to
be the very first ones. I was careless when typing and didn't think about
gmail creating a link out of it.

Hi
Every one that I found showing enough detail had the bumper with feet rather
than the feet that clip into the case. A couple of power options are
illustrated (DC and AC) with various option numbers attached.

The instance pictured has the 16-char display option so it doesn't look
like many of the images you find of the 58503A.
Hi
That display is a pretty hard part to fake. It’s not custom enough to be
impossible to find, but I doubt it’s a stock part at your local market.

If any of you want me to post more photos let me know. I have several of every
kind of HP/Agilent GPSDO product. And they are all genuine because I bought
them a decade before the China/eBay/GPSDO business.
Right, I probably should have included some of HP's GPSDO products in the
hpclocks
And 'scope probes :-)

Ok, that’s just plain not fair. I could accept the motherland of bumpers and
handles. Tossing in scope probes … you are not to expect the usual fruit basket
from me at Christmas :)

Ebay is your friend when you need footsies for your old HP equipment... just
search for HP FEET and you should be able to find what you need. As usual, you
will find sellers with reasonable prices and those that think they are made of
25k gold.
