Zenza bronica ETR/ETRs darkslide size

[mimashita]

Hello!
Could anyone share the dimensions of the dark slide for the Bronica ETR/ETRs film back? I have two cameras and none of them has the dark slide. It seems that the market has gone a bit crazy and sellers ask the price of a camera just for a film back... So, i thought I could order them at the hardware workshop.
Will be very thankful if someone can post the dimensions here including thickness and position of the hole.

Thank you so much in advance!

I can let you know later , unable to at the moment as I'm at work .
There is a lug on it as will that has to be inserted before the back can be removed for a different one .

Have you checked the price of 220 backs lately ?
These often sell possibly for the same or less than to have one made .
Buy one of them , keep the dark slide and stick the back back on eBay as incomplete . Might work out that it'll cost you nothing this way .

I have a spare ETR shell and darkslide (two, actually) that I could sell you. That _has_ to be less expensive/less involved than having a machine shop fabricate one for you that has the interlock tabs in the right place.
Send me a PM if you're interested.

Thanks for your responses!
I realized, just as you guys say, there is a small interlocking tab on the bottom of the shell, which must be depressed to release the film back. It seems to be a bit more complicated than i thought (i actually never had a bronica dark slide in my hands).

Seems buying the film back is the only real option

On the long side, dont forget to add something to pull it out by.

The tab at the bottom of the darkslide... push that tab in the slot manually to get the back off.

Good luck.
