Is a 5335A close enough for you?
Here is one in Canada, probably within road trip distance of 25CPS or the dwagon:

I cannot quite make out in the photos what is listed on the options sticker.
Tempted myself, but have already overspent on home repairs and other necessary stuff (according to SWMBO...).
Same seller on fleabay also has a HP 3311A, Fluke 1900A, crimp tools and other items.
Someone (Pat maybe?) once mentioned that HP made some 3311A in metal enclosure instead of plastic. Is that readily discernible in photos? The aluminum and plastic versions of the 3478A are easy to differentiate, but I've only ever seen the plastic version of the 3311A (that I know of).
I have a 3310A, 3310B, 3312A and 33120A. A non-plasticky 3311A might be nice.
Here is the link to the HP 3311A.

It looks to my eye that the dings all show a bright metallic colouring.
However, at first glance, the shape of the case made me think plastic, hence the uncertainty.
Hmmm, on closer look, someone photo-shopped out something from the photo of the top, on the top centre at the edge where it meets the front panel...
