ek1 Square mm any suspected maker?

[gregM]

I have always leaned toward there being some sort of link
between the [] and CD.

The "CD" family is a big one......CD800 with only one core,3 different stamp positions,but only as a pinback.
"Square"-two cores-one of them identical to the CD800,the other one like the one above.Pinback,scewback and double screc with big washer!
"800"-same as square!
But I don't think that "L/59 has got something to do with the Carl Dillenius Metallwarenfabrik...

I told that: during WWI I don't know a mark for the little square, now I learned this is attributed to CD,I've found during the WWII the square, and other symbols, always on L/59.

For sure L/59 (Alois Rettenmaier - Schwäbisch-Gmund) not got something to do with CD

I have to apologize-there is a CD800 with the 2nd Core Type...just found the pics in my database....the stamping is ath the pin(not the typical CD hardware-and the cross is vaulted)

I don't think the square punch mark has been linked to any particular maker as of yet.
