    • Remove cover screw using a spanner wrench.

    • Remove the self timer lever. The internal mechanism will unwind past the installed position when the lever is removed.

    • Installation Note: Temporarily place the lever on the post 90° counter-clockwise to its installed position. Wind the self timer. Remove the lever and place it in its installed position. Release the self timer.

    • Apply isopropyl alcohol to the edge of the leatherette covering to soften the adhesive.

    • Use a dull scraper to get under the edge of the leatherette and begin peeling it off.

    • Fully remove the leatherette covering from both sides of the camera.

    • If the self timer lever can't be removed, the leatherette can be peeled away just enough to access the screws.

    • Installation Note: Use contact cement or shellac to reapply the leatherette.

    • Remove four 4.6 mm flat head screws.

    • Remove one 4.3 mm flat head screws.

    • Lift off front lens board.

    • Note the position and number of shim washers at each screw location. They need to be installed in the same positions during reassembly.

    • If the top cover is still attached, lift the bottom of the lens board first. There is a lip around the top of the lens mount that engages with the top.

Conclusion

To reassemble your device, follow these instructions in reverse order.

There is no real need to remove the top cover in advance.

Gerjan van Oosten -

You're right. I originally included the top cover disassembly because that's the order I use for a more complete disassembly but it's not necessary to get the front cover off. And thanks for your comments elsewhere in the guides. I mention on the main camera page that the guides are for the 23102 models (the mid/late models) but it's good to have more specific notes about where they differ from early models.
