Paul --
Good to hear that you got your 41CV fixed instead of "throwing in the towel" on it.
Just curious: How many "AASC0994 1.2 V 100mAh NiMH 1/3AAA CE batteries" were used for the rebuild? The non-rechargeable battery holder takes 4 1.5V "N" cells, which are readily available in electronics departments, but not generally at regular stores.
I still think it's worth it to get a battery holder from a scrapped HP-41. The rechargeable batteries are economical and convenient only if the user employs the HP-41 extensively to drive peripherals -- something that probably hasn't been done much since the mid-80's, when PC's became commonplace. You might advertise on the MoHPC Classifieds.
The HP-41CX (1983-1990; fullnut until 1985; halfnut afterwards) would provide a modest upgrade to the 41CV, with time functions and extended-memory functions built in as well as more-convenient catalog listings.
There are plenty of HP-41 experts on this Forum; I personally have an early fullnut 41C, a halfnut 41CV, and a late fullnut 41CX, plus a few peripherals and ROM Pacs.
