Terra Tiger / What Make and Year

Only thing I can tell by that that picture is it's later production body of 1st Feldmann or AC one. AC ones had serial number sticker on dash by steering tiller and had AC Logos on rear sides and rear of them. Feldmann had large Feldmann decal on each rear side of body. And serial number on Feldmann were located on right rear side of upper body (behind seat). Most are missing them! All AC ones I've seen and have are always their or you can see outline of it if painted over. Would need to see pictures of inside clutch- jackshaft and picture of axles & housings to tell also. As Feldmanns had smaller axle brg housings and other differences in them. It's probably a 67 model? I would get rid of the twin cylinder engine! You have a lot of work to do. :)
