I'm going out on a limb here, 'cause I have no idea, but I'm gonna say LRD or Dynoport?? Is that a CR250 or an ATC pipe?

i'm leaning away from aaen..my 86 250r had and older aaen pipe and i've seen a few others... the pipes they made a little while back were painted black... it has a similar weld design but still a bit different... i'm gonna take a stab at saying it is either crafted by someone who has a good idea what their doing and the made it from scratch or i'd say its and old school off beat brand that wasn't a popular pipe that didn't put an emblem on thier header? any serial numbers on it? i'm guessing at around an 83 atc pipe or the 250 dirtbikes in that era but it looks to me more like an atc pipe...
