Columbia Type AB mainspring query

Post by Dulcetto »

Hello from UK , I wonder if one of our American members would be able to tell me the dimensions of the mainsprings used in the Columbia Type AB Graphophone ? and would anyone know if the same spring size was used in other Columbia models , particularly the type B ? I need to source a new mainspring for an AB , ( one spring is ok , the other has broken near its centre ) and would be grateful for any assistance in the matter. ( I have a USA shipping address I can use if necessary ) Many thanks .

You are correct - - the mainsprings in the AB are identical to those used in the B.
