• Notes

• The Photofact folder from July 1955 shows as name only Granco 610 and the sticker in the set can also be mistaken for model 610 but a closed look unveils that it's name is 610U - and the back wall shows clearly FM 610U. See photo. There is also the AC model T610 listed by Photofact set 309 folder 8 date 3-56.
