It’s very rare to get scribed numbers on models they are usually either moulded or stamped they don’t look original to me they look more like someones licence number! But I could be wrong just a thought.
I wasn't focusing on that..it is the STAMPED numder ( ! 0 1 ) on the back of tha cabin!It’s very rare to get scribed numbers on models they are usually either moulded or stamped they don’t look original to me they look more like someones licence number! But I could be wrong just a thought.
Sorry some how I missed that photo I would hazard a guess it’s just a production number when built for identification being either / Persons Inspection number , Part number or Die number that produced that part. For example older car manufactures would often outsource parts to guarantee supply and had the same part produced by various outside manufacturers the parts were identical with the car manufacturers name part number on them but also a extra number that was unique to a particular supplier eg 1 , 2 , 3 ect for identification purposes.I wasn't focusing on that..it is the STAMPED numder ( ! 0 1 ) on the back of tha cabin!

My type O...my engine as you might see reads ( 1 0 1 ) as I mentioned others have stated that the number die stamped on the cab could be a series number but no one has yet stepped up and deffinitively stated beyond any doubt that it truely is as such. I have seen early models with single digits and paired numbers, one particular showed a ( 1 3 1 ) another with a single ( 1 ) and a different one with a ( 9 ).Sorry some how I missed that photo I would hazard a guess it’s just a production number when built for identification being either / Persons Inspection number , Part number or Die number that produced that part.

If these numbers are individual production numbers It would be interesting to know how many of the Big Boys Tenshodo actually produced.My type O...my engine as you might see reads ( 1 0 1 ) as I mentioned others have stated that the number die stamped on the cab could be a series number but no one has yet stepped up and deffinitively stated beyond any doubt that it truely is as such.

I had a short conversation with someone who seemed pretty savvy about the subject, with the quanities, no dates and not much to the references to the serial numbers if thet had one, the information is not biblical in the sense that there numerical in a book somewhere from what I read into his discription. There are specific era's of Tenshodo according to years produced, those before 1963 and those after. It seems in 1963 PFM ( Pacific Fast Mail ) the company that became the main shipper of the Model Engine goods for Tenshodo and others had groups of identifiers that were in reference to those model groups which could identify perhaps the years of certain engines but again what I have seen seens to be is more generic and then there are those early engines thast were "custom" built for people and not identified like the group builds if the information I found serves me.If these numbers are individual production numbers It would be interesting to know how many of the Big Boys Tenshodo actually produced.
