HW50 Original version dates

[CapitalBee]

Paul, Pete Evans had one for sale recently, dated 1992.

[Mach 1.5]

Interesting. So I'm guessing 93/95 May have been the last of the screw in block ones? Mach 1.5

The blue book claims the Beeman R8 was made until 1997.
It is basically the same gun with a different stock, so it might be a clue, but I really dont trust info in the blue book that well.

Just picked one up dated 1993. Why do these old ones shot nicer than the modern version? Mach 1.5

Do you mean as compared to the recent 50/99, Paul? Those newer rifles are 26mm bore, the earlier ones 25mm. Can't remember if strokes and piston weights are in Bruce's thread in the Useful Section?

Plus they have the factory honed cylinders of the old screw in rear block guns so the cylinders might be better?

Yes Tony. The older version is much better than the new offering from HW in the shape of the 99. Just need to swap the perfect trigger out for the Rekord version. Nice little flip up safety on this one. I think the safety at the rear of the cylinder came in around 1986. Mach 1.5

The standard synthetic sealed Oldschool HW50 piston weighs in at 200-202 grams, Tone.

Bore X stroke = 25mm X 65mm.

Transfer port = 3mm X 25mm.


My playing with HW50s, if it's any help ? :-

If I did another one I'd just increase the stroke by 5mm by machining the piston arbor to accept a TX piston seal then weight the piston back up to 200 grams.





All the best Mick

Interesting to see that HW used a completely different rear sight on the last of these and never used it on another model. Mach 1.5

Details now on Bruce's thread as long as that's okay, Mick?

Thanks again.

Different internal specs. may help. the 50 is 25 mmm bore can't remember stroke but good for sub 12 if memory serves. The 55 similar with less stroke so rated more for target I guess. Got a 55 in bits at the mo'. Oops! just seen TonyL post.

I'm looking forward to receiving this,been looking for one for a while(years!) I've never tried the perfekt trigger,would have preferred an earlier version,with the finger grooves on the fore end.Being a 92 model,will it have a synthetic piston seal or leather?

It should have a synthetic piston seal --- all 25mm Weihrauchs changed to synthetic piston seals in 1983.
