Eleanor,
these frames are known as Taylor frames, they could be used both for algebra
and numeric applications. I am unfamiliar with the algebraic
representations but the numeric type, which were all basically lead, had a
bar at one end and two lumps at the other. The holes were octagonal and
numbers and minus, plus, multiply, divide, decimal point and equals were
represented by the position of either the bar or lumps. The rest of the
ends on each type were flat.
I have one of these plastic frames and from my days having useable sight,
remember the board was redish-brown and the tray and back white.
I will see if a friend can photo mine, do you want with and without type, in
the board and laying in the tray? I only have the numeric type.

England, draws your attention to the up-and-coming
2012 Olympics on the starting day of which is his
birthday!!
