American pool company but don't know who they are

[zach123]

Hi people,
I've got a DLM professional shaft and a DLM butt but I don't know who the company is and what its worth,
Now I bought it for £15 because the ferrules cracked slightly and he didn't know who the company is but I'm curious as I've googled it and can't find the company anywhere.
I don't really care if its a crummy company as I play really well with it but I would like to know its origin.
Cheers,
Zach
