So far, the only reference I have found to Craig is from Jerry Girard, who wrote, "A. J. Campbell and & I examined the rod and were surprised with not only the quality, but it's delicate nature, clearly a dainty valise rod, each section approximately 25 inches in length, not having been measured. It was made of hickory in the early 19th century British style with brass ferrules and flip ring guides with a brass escutcheon for a spike reel and the butt section fitted for a spike. The diminutive reel is the Irish spike reel style. The rod has five joints and the butt cap engraved 'Craig, Dublin'. Examples of this type of rod are described in the 1839 John Cheek fishing tackle catalog."
Although the rod I recently acquired is not a valise rod, other aspects of the rod that A.J. and Jerry examined match the characteristics of the rod I acquired. The rod and reel combo are photographed with a Zebco Cardinal 4 (medium freshwater spinning reel) for scale. Closeups of the reel have a quarter for scale. The tip guide is certainly a replacement, but the rod shows no indications that it was cut down. The taper of the rod is consistent, and ferrules fit perfectly.
If anybody has information about who Craig was, please let me know.
