Tommy,
I reckon that the arn for that one is...........

174-242 109 1968 . Series 2A c6028D 25321157K
25327181D - - -


only problem is that the date is listed as 1968 but nomclem plate says 1/69???

chassis 2532781D

i checked what i think were other possibilities of that 781 combo eg 137 but this is all that came up....

nice unit..again you are finding stuff...amazing!
