Sorry if I wasn’t clear, I meant they were using London as their business address not on their headstamp. The headstamp then wwas Eley Nobel or Kynoch Nobel.
The catalogue in question is Nobel Industries and is actually 1925. The price list is 1926 I think, but the give their business address as SW1 (London)
I can only ever remember Eley using the Birmingham address in my lifetime so the change must have been before 1960s…
The catalogue is a photocopy but it is with Falcon now. If you want a scan I’m sure he will be only too happy. It only has a pricelist for shotgun cartridges. I would be very interested in getting hold of the pricelist for their metallic ammunition for that period.
I have an on going project on the cost of ammunition relative to income levels for each decade of the 20th Century. In 1926 100 Eley cartridges cost approx 1 weeks wages for the average working man. Thats something to think about.
