Sigma 50 -150 2.8 the ideal lens for a day out on Worth valley railway

I'm going to be putting my 1979 K-mount manual focus Sigma f3.5 21-35mm back on my K10D very soon.... Posts to follow.

Meanwhile, a question for those with more Sigma experience than I --

If you see a Sigma rear lens cap marked only with the Sigma symbol and below it the capital letters "PE", what mount would you suspect it is?
* PEntax?
* PEtri?
* Something else?

The cap for my 21-35mm says, after the Sigma symbol, "FOR PENTAX-K." and was obviously created in a more verbose time at Sigma than a cap indicating the mount with a mere two initials.

This Sigma 28mm f1.8 DG Macro has been stuck on my K-1 lately.

F10, 4secs, with Pixel Shift

F4, 3 secs, seeing how the lens performs on the larger apeture.

F6.3, 13 sec

F11, 20 sec

After acquiring, fixing (loose screws inside) and cleaning a 35-70 mm Zoom Master, I was able to capture this Close Up/Macro shot of a Christmas Cactus coming to Full Bloom at the right time of the year with an added 4X Magnifying Filter

Very nice photographs of a really interesting landscape.

I was taking some test pics with a telephoto of the turrets, but scurried home to get my 10-20mm DC f4-5.6. Tide was helpfully in when I got back, but no longer quite millpond flat. K5, f11, 14mm.
