Hi Folks, I have this unknow nacelle lower, it has a cutout for the handlebar on the lower part - unlike the cut-out only on the top panel on my T110.

[Linked Image]

Can anyone ID it or, if measurements are required to ID it, which ones would be pertinent to provide.

The photo colour is very misleading - its more of a very faded Amaranth Red like colour.

Thanks.

The notch in the top for handlebars, and the position of the hole for the fork pinch bolt appear to identify this as a
nacelle for a 350 or 500cc UNIT construction Triumph, 1957-1963.

That's my guess, anyway. As I remember it, the hole for the pinch bolt is in a slightly different location
for the 1960 - '62 T110 and 6T pre-unit bikes.

One of the fellows on this site has done an extensive analysis of differences in Triumph nacelles,
and i hope he also will reply.

This matches one in my photo collection that is labelled "1958 3TA", which is also the same as the 5TA or "Speed Twin"; if the paint is indeed factory Amaranth, this would also help confirm 5TA. Viewing nacelle from the rear, is there a second hole about two or three inches above the pinchbolt hole? This hole would be to facilitate better cable routing and was introduced about 1958.

Below is a copy/paste link to the post we worked on, many thanks to photobucket for destroying much of the value of that thread......
