Need corrective diopter for Mamiya 645

I finally decided to add the 645 format to my 49 year collection of Pentax 35mm cameras. I need to locate a +3 diopter piece to go in the slide-on eyepiece with the rubberized hood. I can't find any on eBay. Are there any other slide-on diopter pieces for other cameras that will fit the grooves of my Mamiya 645 1000S prism tops? Hopefully, someone has come up with an alternative. Thanks for any suggestions.

In the UK, but... http://m.ebay.co.uk/itm/Mamiya-M645-M645-J-M645-1000s-PRISM-FINDER-EYE-CORRECTION-DIOPTER-LENS-/221739014466

I think that's what you're looking for.

Thanks. I saw that on eBay but the +3 was sold by the time I came across it.

You may try reaching out to http://www.japancamerahunter.com

I know he offers a commission based search of the vast number of used dealers in Japan, but I'm not sure if he would take on a small item like this. Maybe he can point you in the right direction.

You could always go to your local eye glass maker and see if they can custom make something for you. Especially if you can find another one and just have the glass replaced.

I would check on apug in their medium format section and post something there. You might have better luck in that specific forum.
