My partner's father has three mechanical calculators and he's trying to find out if they are worth anything. If anyone is a collector - or has any contact details for one - please let me know, any help would be much appreciated. Facit, model C1-13, serial number 558358 Facit, model TK, serial number 184944 Brunsviga, model 13 RM, serial number 28303 Thanks in advance Nick
