Lister was in production much later than 1929... I’m thinking into the 50’s but I’m not a lister buff despite owning one (for shame). I read recently that the last of the lister works in Dursley England was finally bulldozed just recently. I have a big Ruston 5HR also which many of those are still in use in particularly in the British colonies, pumping water, generating and grinding grains and such. Mine ran a saw mill from its birth in the late 30’s and was retired in the early 2000’s. I still saw fire wood with it. The lister would have been used to charge batteries for a local church. Shut down during the service while they ran on battery.
