Caper, if you are referring specifically to Sc #36 (produced from Plate 1) and not #36B (produced from Plate 3), then the answer is yes. James Allen, a premier student of the 12c 1851-1857 issue, has this to say: "Plate 1, which produced the imperforate 12¢ 1851 stamps of the 1851 issue, also produced a great percentage of the perforated 12¢ stamps of the 1857 issue. The plate varieties found on the 1851 imperforates are therefore repeated on the perforated stamps printed from Plate 1." (CHRONICLE 241, Feb 2014, p.45).
Thanks Dudley. I had come across what appears to be a 5R & 17R1 #36. No catalog value is given for used triple transfers in the Scott catalog, so I'll assume for now they have the same value as the double transfers.
Here are the stamps I referred to (best pictures I can provide right now). The stamp on the left (the 17's) is copied from Siegel and is listed there as a triple transfer variety. The two on the right (the 36's) are mine.
17R1 is not listed as a triple transfer in any of the standard references or by Allen in his Chronicle articles. According to Siegel there are three different frameline entries at UR in this position. Unfortunately, Caper's copy of #36 from this position does not show this area. Neinken's drawing of 17R1 does not show traces of three framelines either. It seems that a confirming copy of this position matching the Siegel item from the Wagshal sale is needed.
