Need Objective Coments on This Crown

[jmb]

Seems the more I try staring at minute details comparing several closely related objects the more everything starts looking the same!  I received an evaluation sample (from a proto batch) 6mm crown from a trusted parts seller who wanted to know what I thought of it.  After receiving it it just looked a bit odd but I couldn't really put my finger on what bothered me so I put it on my "daily beater" Explorer and took some pics.

 

There are some immediate contradictions that really won't be seen but bear mentioning.  The crown is a monoblock (?) construction but the internal thread is for the "old style" tube which I believe is the same as for the 5.3mm crown.  Also, the machining on the back-side of the crown is pretty rough but it really isn't seen.  The crown gasket is of the "flat" variety which is also in keeping with the older style crown.  I'm thinking for an old-style crown the edge chamfer on the back-side of the crown should ba a bit more pronounced as well.

 

The "knurling" is nice and sharp, compared to a lot of replica crowns, overall thickness looks about right, but the "fillet" transition from the edge of the knurling to the face of the crown seems a bit weak.  The main thing that just looks a bit strange is the coronet and "dash" placement.  The coronet seems a tad small and the "dash" maybe a bit high.

 

But, I'm about cross-eyed about now so I'll shut up and post the pics...

It's a 603

Rep 603, they are looking good! When can we order?

I think this could be an improvement on the stock crown Justin. Hard to tell though from these pics alone.

Definitely looking good, if not way better than the older crown.

 

The older crown had a huge coronet and slightly eccentric inner/back slot for the stem, but that was on last year DJ cases.

No idea if that has been changed for the better on your new cases, Justin?

Looks better than a lot of rep 6mm crowns I've seen, but I do agree about the dash looking high. If the coronet is undersized, I'm not noticing it as much.

Here's a gold 6mm crown monoblock that I found in my parts box:

Coronet and dash are slightly different. But fairly certain yours is fine

Did any of the monoblock crowns use the smaller "old style" tube?

 

So, so far the overall impression of this crown is fairly favorable?  I'll pass this info on.
