Having just gone through an assortment of Philadephia precancels, I came upon what appear to be 8 different types:


The first three were relatively easy (61, 257 and 247 respectively).
The second scan seem a bit harder. I think the first one is a Type 44; and the third possibly a type 205 (?) but I can't identify the others, which are probably L-types.
Would anyone care to assist in identifying these for me?
Thanks very much.
