Is this a Stevens Trail Blazer and what parts do you need?
Does it look like this,
Is it a single shot, mag fed, tube fed?
Go to Numrich Gun Parts and on the Savage/Stevens/Springfield page under rifles look at the schematics for models 15, 120, 125, and 63 and see if any of them match up with your gun. This is a link to the page.
They also show a Premier Trail Blazer, but it is magazine fed.
You may need to take the receiver and barrel out of the stock and look for other markings to further identify the rifle.
Can I Send You Photos of the bolt assembly? If so I need an e-mail address
It looks like a Mossberg bolt to me. Is the safety lever on the top of the stock, by the rear of the bolt, swings side to side. Red and green dot for safe and fire?
I just went through a 1200 page catalog trying to match up your bolt. The closest thing I can find is the Savage model 15 because of the cocking handle. Send the pictures to Numrich Gun Parts customer service and ask them to try to match it up. You can call them at(NNN) NNN-NNNNand they will tell you where to send them. Also send to Havlin Sales & Service and ask them to do the same. http://www.havlinsales.com/
Sorry that I couldn't be of more help, but without a brand or model # XXXXX is pretty hard to do, especially when the gun is not on my bench.
