That gun doesn't look like the No. 70 Trap Grade in any of the Tobin Arms Manufacturing Co. catalogues I have. Here is the cut from Catalog No. 110 --
Here are a couple of guns I would call No. 70 Trap Grades --
17351
17351
15174
Then again, probably half the Tobins I've looked at over the years don't match the catalogue pictures. I saw one of those dog head Tobins at the winter Las Vegas show a few years back. Also, the Canadian period Tobin catalogs only offer the No. 70 (or any of their hammerless guns) with a straight or pistol grip. The half-pistol grip is only cataloged on the hammer gun.
My Tobin articles were published in Volume Five, Issue 1, and Volume Eight, Issue 1, of
The Double Gun Journal; Volume 39, Number 12, May 1994 of
The Gun Report; and Volume 34, Number 3 of (the Canadian Journal of)
Arms Collecting.
