Hello Vidar!
I have a sales brochure for 3 P7 projectors..... P7T Universal 300, P7 Studio and the P7 Synchron. It's 16 pages, and if you are interested I can send you a scan.
The big difference between the P6 projectors and the P7s is, in my opinion, Bauer added auto threading. Of course, everytime I make a statement like that, someone will come forward with additional changes. In the pictures they look similar in the layout of controls.
The P7 Synchron is somewhat similar to the P7 Studio, they both have synchronous motors, optical playback, and magnetic playback and recording.
I also have the instruction manual for the P6 Studio that may give you some useful information on using your P7 Synchron. If you are also interested in that manual, I can also send you a scan of the 26 page manual.
I'm a new member, but I'm set up to receive private letters. Long time lurker.

Bauer P6 built in the 1960....
3 main types:
1st: with 100V 500W P28s bulb
2nd: with 24V 250W bulb without mirror
3rd: with 24V 250W ELC (with mirror), same on all P7 + P8
Amps with different wattage and speaker specs (high ohms!)
All P6 have auto threading. Several modification to film entrance area, mainly in order to avoid film threading when film is on end. Several modification last rollers at end of film channel.
1st and 2nd (earlier types) have 3 claws, later models 4 claws.
All P6 + P7 have fixed 3 blade shutter or automatic switch over 2/3 blade shutter (3 blades at 18fps and 2 blades at 24 fps) with gives higher light output at 24 fps. (auto shutter = more expensive). Back cover fixed by many screws 7 ?
Exiter lamp cover modified.
3rd model: Back cover hold by 3 screws, only. This model is rather identical to P7, e.g. modified sprocket wheels, easier to adjust.
On P6 1st + 2nd Claw arm and cam was oiled from small oil container without cover (projector always upright!!)
From P6 3rd model + P7 + P8 a larger oval grease container with black cover had been employed. Earlier P6 models could be converted to grease container (conversion kit).
Colour of grease changed from dark grey to white grease with very improved performance.
Bauer P7 built in 1970....
further modification to film entrance area, pressure piece modified, Amps with higher wattage and lower ohms speaker out.
Door in front of lensholder /film path can be left off or open during projection (very convenient), were not possible on P6!
Modification to lens holder, to avoid burnt, deformed pressure piece, earlier models could be updated. All P7 have 4 claws (if not be replaced be 3 claws during repair)
On P7 and P8 pressure piece is lifted during auto threading, to make threading foolproof even on thin, soft mylar film
P6 and P7 have AC motor, 18 / 24 frames/sec. by shifting flat belt, improved fix lenses and zoom lenses,
Back cover hold by 3 screws, only (service friendly)
Many improvements inside projector and threading path (more relaiable, easier and faster service work)
P7 has been built over long period and in high quantity. Many spares still available.
Bauer P8 built in 1980...
almost identical to Bauer P7 beside following changes:
P6+P7 AC motor now replaces by DC motor and electronic control circuit board,
further modification to pressure piece, improved lenses,
Later models have additional friction (new, more parts)
Front painting now in gold, was silver on P7 and gloss silver on P6.
Back cover on P8 is in black colour and increased thickness.
Later models called " P8 Professional" have additional main switch to shut off transformer.
All P6 and P7 and earlier P8 models consume wattage vs. transformer as long as main plug is connected to wall outlet!!
All P8 have 2 blade shutter for bright image on screen. Disadvantage on 18 fps, flickering.
PS: P8 selecton has 3 blade shutter and is a total different maschine compared to P8.

I'm no expert but I can add that as I currently happen to have two P8s (I'll sell one sometime), I have noticed several differences between the two, but suprisingly neither have the gold colour that Josef mentions - both are silver. Both of mine also have magnetic sound, so I don't know if that applied to all. It seems a shame that they stopped using the shutters that automatically change from 2 to 3 bladed, depending on the speed, that was a feature of the P7 and the Rank Aldis equivalent.

@ Maurice,
Your P8L was built in 1988.
85% of Bauer 16mm film projectors have optical and magnetic sound.
They are defined as following:
P6 xx
P7 xx
P8 xx
e.g.
P7 S = silent, no sound
P7 L = optical sound, only (most have 24fps, only !!)
P7 TS = optical and mag. sound, plus still projection (most projectors are of this type)
P7 MS = optical + mag. sound, as well as mag. sound recording, plus still projection
Bauer P6 did also appear as P6 H = manual threading, opt. + mag. sound. The Bauer P6H is rather seldom.

If a Bauer P6 still has old oil reservoir (rectangular, without black cover) I wouldn´t recommend to fill in any oil. It will result in a mess inside projector, as oil spreads everywhere around. Better to top up with special white grease as recommended by Bauer.
@ John
sorry for late reply. I just saw your question.
I don´t believe that you will get the greases and oils localy in your area. We sell it, so you know one source, if needed.
Picture could be sent to kt_welsch - at - web - dot - de
Please note, that I am by chance online, only. I have to visit a friend 6km away and emails are checked seldom, as I have to be spent more then 20 min. for deleting unwanted mails,each time. Faster will be by sending letter.
