Hi QuickHitRecord,

I read your excellent post about modifying your Bell & Howell into a single-focus unit.  Inspired by what you wrote I have ordered a Bell & Howell in hopes of replicating your modification.  I was hoping that you might be able to provide some additional info on the customization you did.  Particularly details on the 'multi-start thread' front housing you had fabricated in order to reduce the number of rotations required for focusing.  Did the machinist you worked with create any schematic or CAD file?  I am grateful for any/all info you could provide, or just any advice or observations in making & using your B&H lens.  I'd like to document the process it and post it back to the EOSHD forum (provided I can do it successfully). Thank you for your time and consideration!

Best,
