Here's the reply from Morgan at Camera Leather,
'You can order any of the materials we have in stock for your Epson. The factory covering is a molded piece, and our aftermarket kit will give the camera a slightly thinner circumference. But it is not an issue, really. The new covering fits nicely inside the edges of the top and bottom plates. There is an issue with the molded back grip piece, and here is what I have been letting other RD-1 owners know about the issue:
We strongly suggest you leave the original molded part on the back. Removing it creates a condition where, if you are holding the camera with your right hand without a strap, your thumb will push up to the card slot door, and if it opens you may drop the camera. This has been observed by one of the two photographers that have been beta testing the RD-1 kit. It's enough of a concern that probably we will not offer anything for the back once the RD-1 has a real dedicated section on our site.
I'll be happy to include the 2 -piece section for the grip area on the back, as long as you understand and accept the limitation and risk in applying them. Otherwise you can just apply the front sections and not worry about it!'
Looks like I'll order soon 🙂 What leather is the question?
