Bath - Undated Roller Cancel, Reply Coupons and Premium Bonds

Some slightly more mundane items this time, though this first sheet with two examples of an undated "BATH / SOMERSET" roller cancel used on envelope, one in black and one in red, is not common.

However these next items are much more widespread, examples of an International Reply Coupon and a Commonwealth Reply Coupon with "BATH / SOMERSET" single ring handstamps from 1965 and 1970 respectively.

This Premium Savings Bond has a "BATH   SOMERSET" single ring handstamp from 1970.  I've looked but I don't think it's won anything.
