How you can help

---

• Correct any errors I have made, especially regarding models I don't own and haven't seen.

• Provide information on differences (over time) of models I do have. For example models that later had X-sync shutters or PC connectors rather than ASA, more lens surfaces coated.

• Provide information on other models, listed or not, and on variations in those models (eg. III vs IIIb).

• Provide dates and prices for other models for my Timeline.

• Provide photos of other models or ads from old magazines. Credit and copyright notice will be provided. (Information credits will also be provided if you like.) Let me know if you want your email address listed, or just your name.

Thanks - Greg E.
