That is great information. Thank you so much. I was hoping to get $100, but maybe bump up to $150. Would you recommend me posting on the Classified here?
The safety doesn't look right for T01. Diana did have non modular triggers before they came up with the T01. There were not necessarily trigger identifiers on the receiver. I don't believe Diana started that until the T05 series.
The gun in question does appear to me to have the raised (or add on) scope rail. That is not a surprise as my 1969 Model 35 also has the raised (add on) scope rail. That rail is the same as the one used on the later T01 and T05 series rails. The scope rail changed with the T06 series rifles but is still an add on.
