Astragal planes are mentioned in the 1862 Catalogue, but with no item number, and for that we have to wait until the 1873 [ or possibly before] catalogue when they are called #857. In 1897 they are shown as #984 and as being available up to 5/8″for 2/4d and every 1/8″ to 1″ were 3d. extra and 4d extra above that 1″ size. In 1909 and 1921 the same range of planes were offered but with #3000 being assigned. The basic plane up to 5/8″ was 2/6d +3d, +4d.
1928 saw a reduction to 1/2″ at 5/- +6d, +8d. 1938 was the same price for the extra sizes with a base price up to 1/2″ of 7/6d. By 1959 #3000 was 25/- with 1/ 6d. being charged per 1/8″ above that 1/2″ size.
They are still listed in 1962 but not in March 1964.
