And here is this one:

PM Brillante, serial number M3931-B

Acquired today from a thrift store. Wood is not cracked or dry that I can see. Joints feel loose. Pad seem fine but I do not play clarinet. The rings look silver plated.

Hi, Iím new. :)

I lifted this off an eBay auction. I didn't buy it but thought it would be pertinent to this conversation. Its not an exact date of manufacture but it gives an approximate date.
Only happy mistakes here.

I purchased a Penzel Mueller Bb Clarinet on Ebay and am in the process of restoring it.  The clarinet is marked "LP" and "B".  SN is 11832, so apparently it was made ca. 1935.
This was one of my earliest restoration attempts and I made mistakes that ruined two of the key posts.  Essentially, the posts must be replaced or remade. Then fitted to the body and drilled, faced and tapped for a new rod.
Background of the opportunity to learn: When I received the instrument, the Hinge Rod was stuck in the posts and was too short, driven in by someone who broke one of the slot tangs.
Mistakes made:  Tried getting it out by grinding a flat on a spare rod to mate it to the remaining slot - used it like a screwdriver but couldn't get it to budge.  Then, clamped the joint in my drill press vice and drilled out the rod, which messed up the hole in the post when the bit drifted.  Don't recall the exact sequence of subsequent events, but I believe I may have gotten the posts out of the body and then in trying to extract the thread end of the rod - broke it off.  Drilled it out messing up the hole again.  Silver soldered some brass rod into the holes, remounted the posts and tried to drill through one into the other.  Of course, I don't have the proper equipment, so those holes didn't work either.  Filled them both with silver solder and set the project aside. 

That was a few months ago.  In the meantime I've learned a better way of extracting impossible rods - cut between the hinge and post at the slot end with a jewelers saw, remove that post from the body and then twist out the other post using the remaining rod.  Then soak the rod & post in penetrating oil and gradually work the rod out.  Reface the cut post and add a little silver solder to the cut hinge then reface that to fit between the posts - ream to fit the new rod.  I learned about this from a nice professional SaxProShop technician when the second problem arose.

I now have a joint mounting jig and cross slide vice for my drill press, so with the judicious use of a very small machinist jack that I will make from a screw, connecting nut and stop nut, I could attempt another drilling.  However, I'm concerned about the strength of the threads being tapped into silver solder/nickel-silver.  And of course, I might mess it up yet again.
Is it worth fixing? If so, any ideas of someone who could tackle the job, or of another approach.

Thanks

Just for current standings on this thread. I was wondering if this was still an active course of investigation and record or is it defunct. I am going to assume one of two things has happened. Silver sorcerer is no longer walking among us. He is extremely busy and not able to complete his research or something along those lines.
With that in mind is anyone carrying forth on this or is it a dead subject which people unknowingly think is still ongoing. Personally I think it is of tremendous value as to what has been done already. No I am not the sort of person to further it but I can appreciate the effort and what has been done.
If  no one is actively managing it maybe it would be time to post something to that effect. This way people contributing to this thread know further information is basically falling on deaf ears.
Is there anybody out there...
Only happy mistakes here.

Thanks for your comments. I apologize that this thread is not better moderated and followed.

This thread was decided to be made Sticky because of the wealth of information contained within. One of these days, I hope we can collate the information into a more unified and easy to navigate format.

Unfortunately, I am not the expert in PM instruments. I will try to reach out to Silver Sorcerer and see what we can do.

Thanks for the feedback
