Looking for Technika lens board drilled for Copal 3.
You might want to state whether you want center-drilled or off-center... or maybe it doesn't matter. You can buy either type from eBay for $12-15 (generic).
Center-drilled preferred but it doesn't really matter.
i think, i've got several. need to look
