It is actually a Sheridan ' C ' Series Blue streak in 5mm which is 20 caliber. I never owned a 20 caliber and I have like two dozen fine pellet and BB rifles. I did a little research and found it was made in 1978. I do know Benjamin bought out Sheridan and the Crossman bought them out. Sheridan was purchased by the Benjamin Air Rifle Company in 1977. That company was purchased by Crosman in 1994. All Sheridan air rifles Model A, B, and C are multi-pump, single shot, bolt action, breech-loading, and.20 (5mm) caliber. Muzzle velocity figures are for Sheridan's standard weight pellets of 14.3 grains.).
Hi, Dale,
I’m a bit confused-a .177 Sheridan? I am not aware of vintage Sheridans being made in any caliber but .20, if yours is truly a Sheridan .177 I would love to see a picture!
There was a guy making a very well-designed mount for the vintage Sheridans as well as the current and vintage Benjamins. He seems to have dropped out of sight, but I emailed him at his old address and am waiting on a reply.
Here’s a few pics-his mount was called the “integrabase”

I cut mine up in order to mount a new front sight on my Sheridan-old one had been broken off.
Dale,
One of the most popular upgrades for the Blue streaks is to mount a Williams peep sight. You can get one from Midway-

The later Streaks were drilled & tapped for this sight, I think the older ones require drilling & tapping to mount it. If there are two threaded holes in front of the bolt on the right side of the breech, the sight will fit with no gunsmithing.

PS- You may already know this, it’s a good practice to store your gun with one or two pumps in it to preserve the seals.
