This is one of the many 1950s Japanese pens made to look like the immensely popular Parker 51 Aerometric fountain pen. Some Japanese manufacturers essentially copied the Parker 51, while others made pens with similar visual cues such as selective or modified use of the hooded nib, the arrow clip, and the cap and barrel shape. Many of these “homage” pens are found with open nibs and are made of different materials than Parker used. This 5 3/8 inch long squeeze filling pen would fall into that latter category. The maker of this pen is unknown, but they put some effort into making an interesting pen for their prospective buyers, probably school kids. The clip and squeeze filler are direct knockoffs of the Parker 51 Aerometric. The nib is a conventional stainless steel open type. The elaborate lacy design on the cap and barrel may be etched rather than engraved as it’s not very deep. I doubt it’s hand engraved. Seeing the clear parts, especially the clear grip section would signal to collectors today that this may be a demonstrator pen.
