Tested HP 41C Hewlett Packard Calculator & case w/ Financials Module & 2 Memory

Description

Up for auction is a used but tested HP 41C calculator, a case for it, 2 memory modules and a financials module. More specifics below.
Included (with more description):
HP 41C in good shape, working (testing specifics below). two of the rubber feet are missing from the back, but looks like they can be ordered separately for around .  There is also sticker residue on the back upper right right below the serial number. Also looks like the former owner scratched their name in the same area.  Not sure if it is standard or not, but there is a piece of Velcro on the back of the battery compartment. Inside the unit behind where the batteries go, there looks to be what's left of a sticker.
HP branded case with foam at the bottom of the case. There is also a small loose tag inside that says Made in USA. Looks like that may have come from the case.
2 memory modules: HP 82106A - Made in Singapore
1 Financial 1 module: HP 00041-15004 - Made in Singapore
1 empty slot filler
4 Energizer N-type batteries I bought to test the unit which did not have batteries in it previously. (will include original packaging, but obviously I opened them to perform the test)
Testing performed:
Beyond just turning on the module, I Googled "how to test hp 41c" and came across the following test.
HP Forum Archive 15 (https://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv015.cgi?read=87317) - In that post, I ran through all of the tests listed and all worked as expected except on the [XEQ] [ALPHA] S I Z E [ALPHA] 0 0 0 test I got Reg 127 but I ran the test with the modules installed.
I also found the service manual for this calculator (http://www.decadecounter.com/vta/pdf/HP%2041C-CV-CX%20Service%20Manual%2000041-90472.pdf) but looks like there is a module required for that, which I don't have.
If there is a test you would like for me to perform and post the results, please let me know, but I do believe the calculator is working as expected.
Thanks for looking and please let me know if you have any questions. I will do my best to answer them.
