Want to Buy Alternate battery supply for Pentax 67

[GlenviewJim]

Looking for source of battery power for Pentax67. Cold weather eats up normal batteries so looking for either the pocket adapter or battery holder and I'll make one.

Two CR123 batteries in series would provide 6V (same as 4LR44) and superior cold weather performance. CR123 battery holders aren't hard to find either..
