I have not yet photographed these fixtures, but plan to soon...they are not in my everyday neighborhood, but exist "off the beaten path" near where I live...

In my past 2 years of sreetlighting, I found a few scattered fixtures among the rest that are vintage, such as:

5 OV-20s, I'll probably get three of them 

More than 5 OV-14Bs, I'd be able to get only one of them.

An OV-25 Silverliner still in service, 400W HPS

5 Landmark model 25s, two of them has been replaced last fall, so only 3 left.

Nothing old left around here for roadway lighting,just some old private fixtures:

LM Unistyle400 Mercs. (parking lot)

LM Styleaire Mercs. (parking lot)

Westy OV-25 Silverliner (private fixture)

Westy OV-14B (private fixture)

I did an interesting find yesterday: A Sylvania R37 with an original M250A refractor!

-OV-15 (a WHOLE LOTS OF EM)
-GE M-250 (a LOT TOO! Mostly grey internal photocell but town near me has a lot of silver ones with remote photocell)
-GE M-250R (again a lot also)
-GE M-400 (in both silver and grey mostly with remote photocell)
-very good number of OV-10s (they weren't too common in most places)
-GE M 400As (both in HPS and MV)
-LM 150s (usually found in MD state highway poles)
-Tudor OV-15s and Tudor OV-25s
-LM 175 and the less common LM 400
-a bunch of open bottoms most common is the MO-8 then the less common of M-100 and PEMCOs
-GE M-1000

I mainly notice the westy OV-25s and silverliners are abundant in the older parts of town (and relamped too!) as well as vintage fluorescent gas station pole lights. I also see a bunch of 80s and 90s HPS 250w fixtures on koke mill road and wabash.

Oldest are 60s/70s small Mercury lanterns, that i dont know who made. They have few different shapes but all are the same basic construction - sheet metal top on a cast aluminum base, with clear PMMA bowl. The gear is in a gearbox at the base of the bracket

We have also a ton of 175w bucket lights by norelco, ITT, cooper, Thomas and betts, joslyn, etc. the rare(ish) bird I'm after is a silverliner.

We have plenty of OV-25s, M400As and A2s (with the occasional M400), ITT/T&B/AEL 25s, and NEMAs. Many of these have clear MV lamps. I also know of two GE Form 400s that still run every night, still 400W MV with the old external ballasts.

Not a street light but a shop in town has a cryselco 4 foot fluro fitting from the 1950s probably and another fitting from the 1960s the rest are more modern  the electrical wiring in the shop I think dates back to the 1930s

Here are all the "vintage" streetlights in my area that I've seen:
Quality Lighting Design 114-24B (They are everywhere.)
General Electric M400s (In a variety of styles. Mostly on the highway.)
American Electric Lighting Series 153 (Not super common, but still a decent amount of them.)
Cooper Lighting TRU Tribute (Also very common.)
McGraw-Edison Unidoor 250 (Only a few.)
Line Materials Unistyle 250 (Just two.)
American Electric Series 25 (Only 3.)
Revere 2600s (At least 5.)

Over here there are some older post tops dating from the 60s to the 90s (wyt-ray post top, gec bathurst, gec Burnett, etc..) and a couple of 90s side entry minor road lanterns (Namley a Sylvania B2224). There are still a few mercury lit main roads around Canberra, though they're extremely rare, being found in only one area.
