Some recommendation to post, the camera isn't working properly. Why does this receller think is good for his business to sell faulty cameras. But with a new battery?
Also I think the ZMII plate doesn't belong on the camera. It has an Angénieux 6-64 and there is no de-clutch control. The left leatherette body panel seems more like a very late edition 4008, mind the feetcounter window. The cover on the drive-axis is also a late verseion. So, it is a very old or very late camera. Or parts have been rearranged It could even be a ZMIV late edition
No to start about the deep scratches which would be very difficult to get even when on purpose.
And aren't these Li-Ion batteries to be charged off camera?
A) Where did I say I recommend purchase of this specific 4008 eBay camera? Exactly, so no need for the officious formulation towards my orignal post you chose to open with . This was about highlighting to Mark Day the price difference between a 4008 kit in beaten-up condition with high cost to get back to order, and a 2008 kit in excellent cosmetic condition that may be less expensive to do a CLA on – both with the same lens.
While Beaulieu cameras are more maintenance-demanding than any Bauer, most Canon, and some Nizo, I own 4008 bodies for over 25 years and they run flawlessly. Can't say the same about that damned ownership of a 6008 (never again! ). It's not a marque for casual beginners, but absolutely worthy of recommendation for beginners seriously dedicated to exploring Super 8 to the max.
C) Not every ZM II came with the Schneider 11x6mm by default. You could order the Angénieux 8x8mm as well. The novelty for the Angénieux bundled with the ZM II was the new bi-tubular Beaulieu Reglomatic. The Schneider was exclusively introduced with the ZM II, and remained optional on the ZM IV.
D) While every ZM II has the exposed motor-shaft/sync-sound socket (over the prior ZM), not every ZM II model has also the 'film wind locking button' or friction brake, which when pressured declutches the motor and thus enables the lovely manual rewind feature.
In fact, the exposed motor-shaft was introduced by Beaulieu with the ZM II primarily as a sync-sound socket so that broadcast-standard Pilotton Synchro-Pilot or Erlson Contact-Switch accessories could be inserted.
The development of the rewind feature via the friction brake came at a slightly later stage in the production. It was mainly inspired by and pushed for by Ritter, Germany's Beaulieu importer. I don't have the serial number at hand from which this became standard for production, but can look it up if you can wait until second-half of June (am travelling right now).
Incidentally, it also became a retro-fit feature offered by Ritter to its customers for already sold ZM models. They would swap out the body panel for a ZM II one to gain the exposed motor-shaft, add the friction brake, and of course threw in a new ZM II badge. You will find lots of Frankenstein-modified 4008, 3/5008 and 6/7/9008-series cameras that came out of Mannheim, and many Europe-based ZM IIs started their life as a ZM.
E) I fail to see a difference in the leatherette texture, however, the cover for the motor-shaft/sync-sound socket is a standard replacement that was handed out since the mid-1990s, as is the plexiglass cover for the footage counter which lacks the chrome-coloured ring. These spares as original parts were already highly valued in the 1990s, and people were put on waiting lists at Ritter for a leatherette'd socket cover. Hilarious stuff.
F) Battery packs can be charged inside the camera by plugging the battery charger into the uncovered socket next to the eyepiece. However, using the external battery container for charging should be the preferred method. For LiIo and NiMH, it all depends on the charge current management logic of the charger, not on the principle of charging through the camera "wireloom" itself.
P.S.: Note the sticker in the cartridge compartment: "Ritter", the sticker type they used shortly before going bankrupt in the early 2000s.
