Another I.D Attempt

[Benelli B76]

A bit strange and with this particular rifle you have to pull the trigger with a mix of two stage method with a bit of smash and grab mixed in. It would deffo benefit from a hammer. I was going to fab something/Frankenstein a hammer. I'm not entirely sure wether I should even be using this rifle as a go to i just do basic maintenance and point. Iv polished some turds in my time may be I should furb this up like a gent treats a lady! Excuse my ignorance Baz. what is an TAC valve?

David.

TAC was the original name for the BAC, Brocock Air Cartridge which you probably know about. These are metal cartridges which contain high pressure air filled by a pump or air tank. The pellet fits in the end of the cartridge and fires when the valve in the base of the cartridge is depressed.

Fascinating, and great info, esp from Lawrie.

I suggest an early chrono test.

I need to find out bore specs 5.52 push through the barrel with ease and I mean ease guys.

I think that Tac stands for Tandem Air Cartridge

I was told by someone who knows about such things that William Boyle tried to sell his single and multi pump designs to Webley and Scott. I believe about a dozen or so prototypes were made with W&S Service stocks. I was told the late Ray Hill contacted Boyle in his later years with a view to extending his research on the matter but Mr Boyle didnt want to speak of the episode and spoke of W&S with utter disdain Hope this helps broaden the research.

I've received the following from John Atkins, and reproduce it with his permission:



When looking on AG BBS I saw a thread headed: 'Another I.D. attempt' about the later type, William Robert Boyle pneumatic and was interested to see a photo. of another example.


On seeing one with differences, plus the metal parts of another, in the Wallis & Wallis Catalogue for Sale No. 495 back in October 2006, I showed it to my friend, the late Webley specialist John McCrossen. I fully expecting John to be enthusiastic and wishing to bid for the rifle - but for some reason he didn’t show much interest; maybe as it was not really directly Webley connected. As he had several other, earlier 1944 Patent single-stoke Boyle rifles, including the original silver finish Boyle rifle that Jesse Foster and I found for him, plus Webley blued versions, I was quite surprised that he initially showed little interest in the rifle, as to me, it had to be connected with the inventive Mr. Boyle - who also designed the then futuristic dashboard of the Rover 2000 car, as I've mentioned before in articles.


However, on seeing the rifle later, John kicked himself for not bidding! I think our friend Mike Sharp won it, but I can't recall clearly. I know there was a lot of paperwork with it that I ended up seeing, but I see a lot of airguns and airgun related material and it's hard to remember everything. I may even have copies somewhere plus the 1950s Patent.


Anyway, I'm sure Wallis & Wallis won't object to me scanning from their October 2006 catalogue regarding Lot 1330, should you feel it might be of interest to add to the discussion. Notice this version has a more modern butt - rather than that the old Webley ‘Service' Mk. II style stock as fitted to other Boyle rifles. I wonder where the others in the batch are?

Cool gun. I would say a very "English" take on a Crosman model 140.

Boy, that long pump looks like it would take some effort.

Looks like a blow off valve. Assume that the little silver bit in front of the trigger resets the exhaust valve.
