Pentax SV mirror box design differences

Hi all, I'm after some Pentax S series expertise.

So, I currently have two SV bodies.
- #1940838 - red 'R'
- #836696 - red'R'

They appear to have slightly different mirror box designs.


#836696 (left) has a much shorter baffle.


#836696 (right) has a lever not present on the other body.

Any thoughts? I am aware of differences between red 'R' and green 'R' bodies to allow clearance for the 50/f1.4, but my understanding is that two red 'R' bodies should be identical.

Thanks, Nick

My "red R" SV (ser #1865059) has a baffle that impinges about 7mm into the opening. It also has a mirror box more similar to that of your later serial number body. I Can't be sure about that last due to quality of the photo. Mine has a slot near the area of the arrow with a smallish pin that protrudes very slightly into the mirror box.

I think that in the early days, Asahi made mods as each model was in production rather than having a fixed point-in-time design as tends to happen now. I have SVs and S1as that have subtle differences also.
