I have a Bauer C2A which was in perfect working order , except that the battery compartment door had cracked .
I was able to use either gaffer's tape or a velcro strap to keep the battery door on , but the velcro tended to loosen over time (so did not maintain firm contact of the battery terminals against the batteries) , and the tape method was unsightly. Neither solution was ideal.
I located a supplier in France who has Bauer spare parts , http://www.cine-super8.net/ .
I ordered the replacement part from Cine-Super8 (cost with shipping to the U.S. was about $21.89 dollars / 16.20 euros. The base price is 9.00 euros ) . This is more than I paid for the camera on eBay ($15.00) , BUT for me it was worth it to have the camera complete again , without the unsightly and awkward tape or velcro.
Cine-Super8 shipped the item quickly and I just wanted to post this link for any other Bauer C2A owners who have experienced the infamous battery door piece breakage and would like to have a source for replacing the part.
They have parts for other Bauer (and Nizo) cameras :

The part for the Bauer C2A is Bouchon de piles Bauer (4 piles)
Bouchon de poignée de piles (4 piles ) pour les caméras BAUER anciennes muettes de la série C1, C2, C2A, C2M, D1,D2, D2A, D2M
I'll probably purchase another one to keep on hand if this one ever breaks.

These are very nice cameras, with elegant styling . Bright, clear viewfinder and easy to focus. 12, 18, 24 fps (and single frame with cable release) , auto and manual exposure . Lens: Bauer Vario 1.8 / 7.5 - 60 mm zoom .
They can usually be purchased for between $10.00 - $45.00 on eBay , but frequently have the broken battery chamber door. (ask first if the seller doesn't mention it in the description ! And of course always ask if the interior of the battery chamber is clean or if it has corrosion)
