The "K" series as such does not exist. It is a made-up name, given for the sake of clarity to the original K-mount Pentax lenses.

They are actually labelled simply as "SMC Pentax"

SMC Pentax = 'K'
SMC Pentax-M = 'M'
SMC Pentax-A = 'A'

SMC PENTAX 1:3.5/135 or smc PENTAX 1:3.5 135mm = 'K'
smc PENTAX-M 1:3.5 135mm = 'M'

This one: SMC Pentax 135mm F2.5 Reviews - K Prime Lenses - Pentax Lens Reviews & Lens Database. There is also a Takumar version if you don't mind using the m42 adapter. Super-Multi-Coated Takumar 135mm F2.5 (model 2) Super-Multi-Coated TAKUMAR/Super-Takumar 135mm F2.5 Reviews - M42 Screwmount Telephoto Primes - Pentax Lens Reviews & Lens Database (mind the model 2).
The classic SMC "K" 135/2.5 is a classic for a reason. It is possibly the most timeless lens I have owned. It is a favorite on film, it was a favorite on a crop DSLR, and now I'm enjoying it on FF digital. Highly recommended.

:P With a classic price of 180 and up. Found a few by doing a search on the designated quoted lacking the "M" on it. Thinking maybe I should hold out for it (right now selling two lens from a different system, so maybe if those get sold I'll grab the 135/2.5).

You could also look for the Super-Mulit-Coated Takumar 135mm F2.5 version it is optically identical to the K version, but you have to use a m42 adapter and you have to get version two which is more rare. You can recognize it by the distance markings. The first distance in meters is 35 in the right second version. In the wrong first version it is 30. I got mine for about €80 from an inexperienced seller in a unlikely e-bay country (Wallonia, Belgium). It even came with the hood. So you have to hunt a bit to find a good offering.

Is the "K" the one marked as SMC Pentax-M ... or something else?
The K135/3.5 has a 52mm filter thread, the M135/3.5 has a 49mm. Here is a picture of my K135/3.5 with case & hood.

I regret getting rid of my 135/2.5 years ago, it was great on film and I never really gave it a good chance on digital.

I have an MX and it always looks wrong to me with anything but the smallest lenses in their class. The Pentax-M 135/3.5 looks right to me. It's also cheap and has excellent performance. For me, even the slightly larger Pentax-A 135/2.8 starts to look too big on an MX. Plus you get the integral hood. You can get a nice clean one for $50, a bargain.

The SMC Pentax 135/2.5 would be my second choice. I think if these lenses came with a KA mount and were easier to use on DSLRs, they'd be $500.

A 52mm thread would be right up my alley in terms of not having to step-up/down what I tend to use a lot.

The Pentax-A 135/2.8 is also 52mm. The Takumar Bayonet 135/2.5 is too, and a lot of third-party 135/2.8s (Vivitar, Sears).

Which is why the Takumar Bayonet so-called 135/"2.5" may really be an f/2.8 lens. [135mm / 2.5 = 54mm, while 135mm / 2.8 = 48mm.] [And 52mm filter threads allow for probably only 49mm or 50mm (at the most) of clear front aperture.]

But back to the original question, "Which Pentax (K) 135mm for Film Bodies", my vote would be for the outstanding K 135/2.5.

The SMC Pentax-M 135/3.5 is a great value. Many of the M lenses use 49mm filters.
Now that you're using Pentax you should consider acquiring a set in that size, too.

If it turns out that you like and enjoy the 135mm focal length, I'd like to recommend my "Lady Luck” (Pentax-A* 135mm F1.8) as a future potential purchase candidate.

It will cost you a bit more, but IMHO, it is one of the finest 135s ever made by Pentax.
