The battery doors on ebay, at least the one I got, was awful. I could have carved a better one out of wood. The plastic casting wouldn't have been acceptable to a Holga owner. Best to hold out for OEM stuff or just use a piece of plastic held in place by the hand grip. Opening the body to swap in a piece of garbage isnt worth it.
Thanks for the heads-up, I was hoping that wasn't the case but it figures. It has a piece of gaff tape over it now so the battery isn't going anywhere but I'd like to get it back to 100%.
I could also use a BS-52 hood, I have a BS-55 hood to trade if anyone would be interested.
Ahhh, you learn something every day. Thanks for the info. I thought all of the winders/grips were interchangeable on AE1/AE1P/A1 too but apparently not.
Looks like Ian has the parts I need so I'll close this thread with thanks to all.
