Hawkes merged with Boosey in 1930

.....Hawkes & Son (later Rivière & Hawkes),[3] a rival to Boosey & Company, was founded in 1865 by William Henry Hawkes selling orchestral sheet music. The company also made musical instruments and spare parts such as clarinet reeds, and by 1925 Hawkes had set up an instrument factory in Edgware, North London.[7] The business, which was particularly known for brass and military band music,[3] was eventually inherited by Ralph Hawkes (died 1950)......

Your drum is probably then pre-1930. Later Boosey and Hawkes brands included Ajax and there are a few about still - I have an 8" deep orchestral Ajax snare that is quite something...

Dear Hawker

I have just found a Hawkes and son "Snapper" snare drum serial number 7176 on inspecting the shell further I found a paper ticket pasted on the inside (see photo) dated 8/5/1924. I assume if your serial number is higher than that it will be a bit younger ergo lower older? I found that this drum was bought for £12 at an auction in may 2015 I spotted it in a shop window and offered £50 and was pleased to do the deal. I was wondering if the snares on these drums were used across the batter side of the drum, like the Brasilian Caxia used in samba? The tension rods seem to be fixed to the batter side hoop which has two 'D' shaped cutaways for the wires, assuming that you are not supposed to play the drum in between eight massive wing-nuts sticking up? Please ask if you need another picture.
