Hi, here are some photos of an Optimus No.96, probably V2 on Bryan Miller's classification, which I acquired recently. It came to me as a tank and vaporiser only but was worth restoring as it looked fairly early, 1930s?. I have added a later burner "basket" and flame-plate, and made the legs this afternoon from some fencing wire: You will note that the pump cap is the early "pressed cup" type. The stove goes very well now that I have fettled it. I think I will leave the existing 80+ year patina, rather than polishing the stove. Best Regards, Kerophile.
