'56 superspeed blue tip problem

[APBT]

Hey guys,
I recently picked up a '56 blue tip superspeed from an antique shop. It is in so good of condition that I question if it's ever been used... Until today. I used it with a lord platinum from a sampler I got. I got a terrible shave! I thought that since I've heard it's very mild that I would get a good shave from it (I'm a total noob), but it's much worse than my ej89l. It took more passes and didn't shave as close and gave me more irritation. I looked at the razor after and I realized the blade had an uneven reveal. I mean to say that while the blade was perfectly straight, one side looked a bit longer than the other side. I took out the blade and turned it around and that didn't help. I then took the same blade and put it in a '56 red tip superspeed I have yet to use and the blade was even on both sides. Could this be why my shave sucked? Is this normal? (It's barely noticeable) Is there any way to fix this or is this just a bum blue tip?

Thanks,
Kevin

That my explain why it appeared unused. The blade exposure should be even on both sides.....bummer.

Update! So I decided to try another blade in it. I put a wilkinson blade in (I have no idea if these are good or not, they just came with the plastic head DE razor I got in a starter kit from italian barber) and the blade seemed even on each side! So I then put back in the Lord blade... It seemed even! After playing around with it a bit I realized that when I close the razor lightly the blade stays even but if I twist the knob a lot it becomes uneven. Thoughts?
