Hardware - Lugs & rods

1961- 64

Lugs (Nut boxes)

The English Rogers Bread and Butter lugs are cosmetically similar to their American counterparts but they are not the same. The English lug is slightly shorter overall but more importantly the distance between the securing screw hole centres is 1/8th inch greater at 1 and 3/4 of an inch, as opposed to 1 and 5/8 inch in the US. Replacement of one with the other would require the elongation of the holes in the drum shell. The forming of the tab at the back of the lug is also different. The English version suffers from a tendency to crack in exactly the same way as the US lugs.
Bass Drum Bow Ties
The earliest bass drums have Ajax t rods (left). The more Rogers-like bow ties (right) were introduced in 1962. These are indistinguishable from American ones apart from being very slightly shorter.                         
Bass drum claws are different to the American ones. The steel is thicker and the shape is altogether more rounded.

Lugs (Nut boxes)

Beavertail lugs first made an appearance on English Rogers in early 1965, a full twelve months later than their introduction in the US. The English beavertail lugs are also subtly different from the US ones, the screw boss being slightly larger in diameter on the UK version, they use a different size of screw and the number inside the casting is unique to English Rogers.

Many bass drums from right at the end of production (late 1966 and 1967) have John Grey T rods. This cannot be due to a lack of supply of the Rogers type bow tie as these continued to be used on Ajax Nu-Sound through to 1970.

In the USA Rogers changed their design of their bass tie rods to a more sculpted shape in 1966. It may be that the use of the John Grey T rod was an attempt by B&H to follow the USA in some way, and make any kind of change it could. There would appear to be a recurring theme here.
