The 3035 calibre was introduced in 1977 & was used in these models (maybe more) - 15505, 16000, 16003, 16008, 16009, 16013, 16014, 16018, 16019, 16030, 16078, 16250, 16253, 16258, 16600, 16660, 16800, 16803, 16808.
As to whether or how well it may fit into a particular rep case, that depends on which factory made the case and/or how much work you are willing to do to reshape it (the case). My franken experience is limited to vintage (mostly 15xx calibre) models, but maybe someone who has built a modern franken will be able to provide more definite info.
