Query: What 49-key keyboard?

I bought this for the combination of good comments and good price.The bag is sized for a very specific keyboard, it seems.IT doesn't fit any 49 keyboard I know and most 61's.THe provider, Musician's Friend wants me to repack it and pay for the UPS shippingif I want a refund. It doesn't make any sense.Oh, the bag? it would be an OK bag if it could fit anything snugly.
