    Yep. Due to mistakenly double ordering I'll have either 2 or three units available. I'm expecting the new ones this week. I can send them back for a refund - I just wondered if anyone locally had need of them before I did that. $20 each including a new battery and a five year guarantee.

    Well, yes. You could do it that way, but it seems a hard way to go, given that units are available off the shelf for $20. My time is worth more than I'd use trying to make my own from those instructions.

    Absolutely correct. The problem is that the drop in voltage from the Wein cells is relatively rapid but most people are not able to detect the changes and so a lot of frames get exposed using meters that are being progressively underpowered and therefore reading incorrectly.

    That's why rewiring is the better solution.

    That should read PX27. Fortunately, both will tolerate higher voltages and you can use about anything you can make fit physically. PX27A are readily available and can be used without modification.

    I think Freestyle has a battery.

    I was looking in an old Freestyle catalog and I saw a battery listed there for some sort of battery that replaced old mercury ones. I don't have the catalog handy, but you might want to see if I'm right or way off base. Ric.

    I have used the Weincell batteries in the past, but over here in Switzerland one single piece comes to approx. US$ 17 which is just way too much.
    Have just ordered the battery adapter from Jon Goodman to fire up my Yashica Lynx 14. Based on my experience with his light seal kits, this should work great. I was lucky, it was the last one in stock, but Jon told me he's going to build them again soon. If I'm happy with it, I'll order some more for my OM-1's and OM-1n's.

    Wein cells are zinc-air, not alkaline. The problem with Wein cells is the price, not the voltage which is both correct and pretty constant over the life of the cell.
