It's my understanding of the earlier models had a different size compression tube. At what point did the comp tube change size? Is there a benefit from the older version to the latter models in this respect? Seems some say yes and some say no.

How many of you own an HW77 with the Goudy stock? I would love to see your pics of them.

Thanks

I have three older 80s guns with the 25mm tubes. The consensus is the smaller piston guns shoot smoother since the piston is lighter, and easier to push being smaller. I have found this to be true, but slightly so. Not a huge difference. 

They do shoot particularly well with a slightly enlarged transfer port at about 12fpe.

The two piston pic is a side by side of a factory 25mm piston, and the 25mm from my Venom, that had the stroke lengthened by about 12mm.  

The older Goudy stocked guns feel lighter and slimmer than the current models. I love these old guns.

I'm not sure the serial number range for when the 25mm to 26mm change took place. But one quick way to tell a 25mm is look at the underlever catch and loading port opening. The MK1 had a ball bearing underlever catch, and the MK2 had a sliding catch. Both had small loading port openings. 

The MK1 has 25mm internals, and I'm almost sure that all of the MK2 guns did as well. Maybe that helps.

Absolutely helps. So was the transfer port larger from the factory with the 25mm? I may have misread.

The Venom is gorgeous, but there is something about the factory K that I really like, maybe in its simplicity of sleek lines...

That is a beautiful example you have! Nice back drop for the photos too.

I think I have found another itch that may require scratching LOL

No, the 25 and 26 had the same transfer port, 2.9mm. 

And yes, those Goudy stocks are nice and slim and trim. The cheek is a little low for scope use, but otherwise they are wonderful.

I have Beeman import HW77K in .20 that a friend bought for me from an estate sale many years ago... shoots great, and is one of my favorites.

Believe it to be a Mk2 with the barrel latch... the serial number (1145xxx) indicates that it was manufactured in 1985-1991, according to the Weihrauch website.

I assume it is the small cyclinder, but I have yet to have it apart... I suspect the original owner ordered it from Beemans with a "super-tune" back when Doc Beeman was in love with the .20 caliber, but I'm not positive... here is a photo of it.

If I come across a fine example like you guys are showing I'll try to grab it. Always wanted one.

From the UK forums:

Originally, rifles before s/no. 1446049 were all fitted with the 25mm set up.

Chase has a nice example, and keeps them Alabamy bushy tails in full retreat with his.  From what I gather the 25mm is the best shooting of the underleavers.

There's a MK2 .177 in the truck right now, waiting for daylight. Season opened yesterday! 😁

You mean the outside diameter of the compression tube? If so, yes it was always the same size.
