Nice write up Louis
That looks so like a Cr 160 when taken down - I guess suing companies for patent infringements was a lot harder back then.
Was the Cr160 design ever patented ?

Merry Christmas.
@lightning22, yes the quality of the Taiyo's is good, but I have a feeling that the power curve will be very steep. There is a big column of CO2 exiting the barrel after the pellet has left, which can't be a good sign, economy-wise. I think I will need to increase the valve return spring strength. And do more testing.
A few differences with Crosman 160/QB78: on the Bobcat, the hammer is cocked by pulling the bolt backwards instead of pushing it forwards.
The Bobcat has a safety, but it isn't automatic like on my 2nd series 160 (I prefer non-automatic; it is annoying to press the trigger and realise you've forgotten to take the safety off!). And in the Bobcat the second CO2 capsule isn't pierced (I must check if a Crosman 160/180/400 tube cap fits).
@Mark, thanks. I think that repairing airguns, especially when the process is straight forward, is my favourite part of the hobby.
@ 45flint, you are probably right. Rudy Merz's designs must be the most copied CO2 airgun designs ever?
The Taiyo Juki Junior is a copy of the 180 by the way.
Crosman 160 2nd series (I think the white o-ring should be on the tube cap btw, and the black one on the valve body, oops):
Possibly the 380 is even closer to the Crosman 160 and QB78:

Some more info:
Taiyo Juki was a trade-name used by Miroku (Miroku Firearms Manufacturing Co.) of Kochi, Japan, making airguns in the 1970's. Taiyo Juki also made Winchester 37 clone shotguns.
They were imported by Kassnar, Harrisburg, Pennsylvania.
Miroku also made firearms for Charles Daly, Browning, Winchester and others.

The best way to reduce the waste of Co2 in your gun is to fit a weaker hammer spring, or shorten the existing one, or another way is to shorten the valve stem slightly.

Thank you Lawrie for the great tips!
I will soon have a little parcel filled with Streak valves and some Sharp ones too for resealing, if possible
First I must wait until the Christmas parcel madness is over lol.
Merry Christmas

A little update:
I found a Miroku scope. Must be rebranded, but for the same company that produced the Taiyo Juki Bobcat.
I think this scope was made after the Bobcat. Perhaps eighties? It is too big for the gun.
The Ednar might be a better fit, but I think the slim German Haweka is perfect.
Collecting scopes is just another disease?
