There are three different types of barrel clamps used in Needham Conversions. None of the three types are modified in any way from the standard barrel clamps used on M1861’s and M1863’s.
The three types of clamps are:
Flat bands held on by stock springs
Convex bands held on screws at bottom of band
Convex bands held on by stock springs.
Out of 179 Needhams in the site, 102 have convex bands.
