It seems like Tobin Arms Mfg. Co. was trying to save money on printing blocks as they used the same pictures for the No. 45 Premium Grade --
Catalogue No. 206. No. 45 Premium Grade.jpg
and the No. 50 Special Pigeon Grade --
Catalogue No. 206. No. 50 Special Pigeon Grade.jpg
This from Catalogue No. 206. The only other catalogue I have from the Connecticut company is Catalogue No. 307 which is virtually identical except for a different cover. I suspect their numbering system means this is their second catalogue and it was put out in 1906 and their third catalogue was put out in 1907. Perhaps their is a No. 105 and a No. 408 out their somewhere. From the Ontario company I know of a large Catalogue No. 110 (the first catalogue they put out and it was in 1910?) and two nearly identical pocket catalogues No. 211 and No. 311.
