Help pricing valuation of some accessories for HP 41 series

[PeterP]

Not much to add other than you have two modules which do not have anything written on them. So one or both _could_ be more valuable, though none looks like a HEPAX afaict.

Might be worth to take them out and see if they have anything written on them and/or put them in a working 41 and do a CAT 2.
