Best option is Ebay. But you deal with fees and bad buyers. Shoot me an email and I will take a look!

This is the camera you have here...

The other one was a single camera made for the first director for ICA.

As far as opening it, I am not sure how to but I wouldn't force it. Just gently try different knobs and buttons.

Unfortunately not much. There is one on Ebay right now in the box and they are trying to get $30 for it.

I would stick it on eBay and let the market decide, make sure you specify it had a CLA!

It is a rare lens for sure, hard to value it for a few reasons. It doesn't have a lot of sale records and the ones there are, are kind of old. Youxin is an expert so it is rare for sure! If I had to guess, I would say it has a value of around 5-700.

Sure, can you email me? redsoxin2005@hotmail.com

Are you selling it?

Insane find! Congratulations!! I would not know where to find caps unfortunately. I hope you do well with it!

Email me at redsoxin2005@hotmail.com

Thanks!

What were you looking to sell it for? I would be interested!
