Help Identifying Springer

[AbyssmalTailgate]

I've got a springer front end I cleaned up and need help identifying the make/manufacturer... I thought it was homemade but have since been told otherwise. It's all welded, no brazing. Super narrow. 5/8" axle holes with a 7/8" stem. The only markings are two "J"s, one on each of the bottom fork legs. I've had a few people tell me it looks like a Jammer because it's similar to one on their buddy's bike. I don't know exactly how much longer it is over stock, but I'd venture to guess 17" since it's 37" from the bottom triple tree to where the rockers are drilled for the axle. I've also since flipped the top clamp and rockers since I realized they were upside down hahaha

Let me know if you can drop some history on it for me, it's a really cool piece! Thanks

Just found this pic via google images, and I definitely think you're right. Mine looks most like the narrow springer in the middle except with different rockers and acorn nuts. Thanks for the confident reply boomboomthump! I guess all Jammers are stamped like that?
