Pukka Bundook,
I found there was an entire issue of
The Museum of the Fur Trade Quarterly devoted to seal hunting, with two featured articles. This was Vol. 35, No. 1, Spring 1999. It is still available from the Museum of the Fur Trade as a single issue. The articles were "Artifacts of the Seal Hunters," which is well illustrated and includes full-length lock-side views and close-up views of the locks of one flintlock and one percussion sealing gun. These are probably the same two guns mentioned by
Elnathan in his post, above. The text indicates this flint lock is "7-5/8 inches in length." It has a reinforced or double-throated cock with a little notch for a dog catch, but no dog. Both the lock plate and the cock are flat and utterly plain, with no visible ornamentation or engraving. There is a pan bridle, however.
Evidently the fractional designations mentioned by
Hudnut refer to the actual, if approximate, bore size, i.e. 7/8 = 0.875", and 3/4 = 0.750".
One additional reference which may be of interest is S. James Gooding's
Trade Guns of the Hudson's Bay Company 1670-1970, pp. 85-86. He illustrates a classic flintlock Newfoundland sealing gun, but discusses the similarity of these arms to earlier "Buccaneer guns." I suspect a few may have been misidentified.
Regarding powder horns, I recall there was another article in a different back issue of
The Museum of the Fur Trade Quarterly devoted to Canadian powder horns, with a pretty good discussion of those used by the seal hunters.
Finding that article will be a project for another day, though.
Here is one more horn to admire. This one was sold some years ago by River Junction Trade Co., of all places, and was identified as a "Maritime Horn." It shows all the classic features of a seal hunter's horn, though, including the cork base and painted butt:
There was a previous thread on the "Antique Accoutrements" forum about a seal hunter's horn, right here:
An Original "Catalina" Newfoundland Powder Horn. The discussion was interesting and initially a little misguided, but our ALR team kept on it until the horn was properly identified.
Best regards,
Notchy Bob
