I have an Ascorlight 1600 that the battery pack was no longer avalible for and after looking for years I found and purchased the 1/2 D cell rechargeable cells to make a new battery pack. it worked fine But now the battery holder cap has fallen apart and my atempts to repair it have failed. Wish I could find a suitable replacement! This was every bit the equal to the Metz back in the day when I purchased it well actually traded a Rollie E36 RE unit and some cash for it. The Rollies had a under rated transistor that burned out and was pretty much impossible to get. Unfortunately like many things Berkley marketed they did not stick with the very fine Ascorlight very long.
