Briefcase Swivel Handle with Nickel Fittings

Hi, Could you tell me what the separation is between the screw holes? I am led to believe by RL Music, who provided me with this link, that this case handle might be a replacement for the handle of the ARP2600 synthesiser case. The paired screw separation on my case is 35mm [1+5/8 inches] and the separation between the two inner holes is 75mm. It's cheap enough anyways so I might just suck it and see, unless you have a better suggestion.Many thanks.
