Thanks Heaps to Brent ,Typak & Buster for your input. I appreciate your help. Unfortunately the tag is long gone. The number I have found is on the lower edge of the regenerator. Again unfortunately the last digit has been restamped with a 4 stamped half over a 3. I thought that the number would be as first quoted, but from what Brent has said it appears that the true number could be 3474 which I thought would be a low number for Australia. There is no 1 in front of 3474. Are there any other places for a serial number?
My best guess is that your no. is 13474 as you mention a 1 in front of 3474. A no. as low as 3474 would more likely be from the Rider Engine Co. or Delamater Iron Works before these two companies joined forces in the mid-1890s as Rider-Ericsson. On the other hand 13474 lies closest in the list to two other Rider engines (made by the Rider-Ericsson Co.) that are or were also in Australia (nos. 13005 and 13849). The closest positively dated engine to these numbers is one in the 16,000s from 1906. It's impossible to determine exact dates as the company records have been lost, but I would guess yours is from 1904-06.
Thanks heaps Brent. Despite all sorts of attempts, there is no evidence of any number in front of 3474, so I will go with your suggestion that it falls in with others in Oz close to that serial number. I have had a new name plate cast and will now stamp it. Am I looking on the lower edge of the regenerator as the only place for a serial number?
I'm sorry but I misread your previous post: I thought you meant "there is no. 1 in front of 3474", but now I see you said "no 1" instead of "no. 1". My mistake; so can't say now for sure what the number is. I also don't know where the numbers are found on other parts of the engine so best to let Buster respond to that. Sorry for the confusion and hope you find another number.
I am A little confused about the location of serial number . You mentioned serial number next to regenerator which leaves me to think it is A Rider engine . On the Ericsson engine it should be near the top of cold cylinder next to support for walking beam .... Or it could be on side of engine next to the top Is it possible to post A picture of engine . ..??? Buster
I'm almost sure it's a Rider engine made by Rider-Ericsson. People are always confusing the term "Ericsson engine"--the engine John Ericsson patented in 1880 (single cylinder with the walking beam)--with "Rider engine"--the twin cylinder engine patented by Alexander Rider from the 1870s onward. It doesn't help that both Delamater Iron Works of NYC and the Rider Engine Co. of Walden, NY made both Rider and Ericsson engines or that the when these two companies consolidated in the mid-1890s under the new company name "Rider-Ericsson" (in Walden), they continued to produce both types under the new name. As you and I know there's no such thing as a "Rider-Ericsson engine", only a Rider or an Ericsson engine that was made by Rider-Ericsson.
So other than the nameplate, where are serial numbers located on Rider engines?
I have seen one engine that had number stamped next to piston seals up on the cold side of engine . I do not think this was factory markings . Most are stamped on front of engine By the cross over where the regenerator plates are located ..this would be Just below the cover plate Buster
