@Pharael . An interesting example. An unusual way of attaching the handles to the legs. This shock absorber on the pump handle (leather?) looks like it was homemade modification. I recently came across a similar invention made from a piece of felt.
@Knee - Yes, homemade leather damper. It came with the stove and so I have left in place. The tank stampings are similar to those in the SRG but not exactly so. I would be dating this stove as circa 1930’s. Pharael.
