BUMPER FIXINGS. 20/25 HP. 84522.
SECOND PART OF "T" SERIES.

We have already sent to you a scheme for the attachment of the front bumper--- N.Sch.3277.

We now send you N.Sch.3280. shewing the attachment of the rear bumper.

As "R" insists that bolts be used instead of studs we have been forced to put the heads(and not the nuts)in the cap. In order to bring the design of the front fixing in line with the back we have changed the bolts round likewise.

If you have already got too far with N.Sch.3277. to permit of this alteration be ing introduced, we suggest that you keep the bolts of the front fixing as now on N.Sch.3277, and and that you use the cap of N.Sch.3277. on the rear, allowing the head of the bolt to be in the counterbore.

We believe, however, that the cap of N.Sch.3280. has the advantage that it gives a simpler surface for painting and polishing after spraying, and so we would prefer it.
