Just bought a HW30 used , has no SS# that i can see unless under the wood . stamped on one side it has , Weihrauch Mellrichstad-Bay also had the rounded hand grip .
Any way to obtain info on this

Bay must be short for bayern

Googled "Weihrauch Mellrichstad-Bay "

Then imagines. And seen several like yours out there mostly auction house .

Sadly thete cookie pop up filling the page prevents me looking deeper

All that nra there i wonder if it was a club gun?

Im sure you found this

Mike Driskoll will know all about it. His knowledge is amazing. All I can tell you is the obvious. It's an old presaftey model, has a rekord trigger and the peeps aren't original. It's a very nice simple gun. The rekord trigger didn't come on all of them back then. So that's a nice option.
Also it's a leather seal model, it'll have a larger Transfer port and switching it to a synthetic piston seal will likely drop the energy potential.
Nice find.

Ron, Would the likely energy drop be from less volume and slower stroke?

There was the Rekord, the Perfekt, and maybe another trigger set up correct?

Thanks for the tip on the synthetic seal conversion, that never gets mentioned that I have read, or maybe I forgot........

this was a gun show , powder burner guns , and this was on one table . I immediately saw the stock and made the offer .

I used to tour Michigan 5-6 times a year, but haven’t been since before Covid-19. I used to scour the Pawn shops, but back then I wasn’t into the air rifles. Would love to make those rounds again. You have the best pawn shops. Crow

it looks like it may be much older than i originally thought .

The stroke will be faster from the lack of resistance. Transfer port science is tricky. I'm still learning about so don't take this as law.

Typically opening a transfer port (TP) reduces back pressure. Doing so it reduces peak cylinder pressure. It also increases what's termed lost volume. Basically it's like using larger combustion chambers in a gasoline engine. Both reduce compression ratio because your fixed swept volume is stuffed into a larger space. This further reduces peak pressure.

Older leather seal guns often have larger transfer ports than synthetic seal guns. The reason is some of the power of leather seal guns comes from dieseling. Leather seals are soaked in oil to keep them conditioned and working properly. That oil burns in a controlled manner (dieseling) and adds pressure (power) to the pellet.

You might ask, Why not use a smaller port in a leather gun? The larger port keeps dieseling within manageable levels. The smaller port would increase peak cylinder pressure and that would cause excessive dieseling or even detonation. Both are very bad for accuracy and the gun's parts.

Over in the UK, tuners there often play with transfer port sizes. When they do it's by very small increments. Tom Gaylord made a R1 with adjustable TP and goes over the results in his R1 book. I believe his final position on it was that it wasn't worth the effort of the custom machining. I don't scare the knowledge these people have so I don't mess with TP size. The only time I've considered it was incidentally to a 177 R1 to smooth the shot cycle. I didn't have the balls to try it.

Yes. I like the read and thoughts. I was pondering a leather seal gun as a daily shooter but after considering the dieseling I think I'll stick to simple composite? seals.

I don't want to dissuade you from buying a leather sealed gun for a daily shooter. There's nothing wrong with them. The seals can last nearly forever. Longer than synthetic seals.

All springers lubed with petroleum based lubes diesel to some degree. It's the level of dieseling that's important. Leather guns incorporate dieseling into the design to keep it to manageable levels. They work just fine that way.

I'd buy one as long as I could visually inspect first hand. If you see one and like it buy it. I would have bought the OPs gun without hesitation.
