Not a lot of information for you- Sovereign seems be Italian, POSSIBLY Tanfoglio, imported by EXCAM in the 80s and 90s. When EXCAM went out of business, their firearms were left as "orphans"- some repair parts were bought by some of the wholesalers, and that seems to be it. There does not appear to be significant collector interest, and I would consider them as "shooters"- possibly in the $100-$150 range.
Winchester made numerous bolt action 22 rifles.
22 LR up to and beyond 50 BMG
If yours is a skeleton stocked VERY light rifle, it was made by Garcia, Bronco is the model. These were made 1968-1978
10-100 usd
Serial numbers were not required by law on rifles and shotguns until 1968. Your Crackshot was made LONG before 1968.
No sn data available that I am aware of.
No. The .22 Long Rifle is not compatible with the .22 Long cartridge. Most .22 Long Rifle revolvers, lever and pump action rifles fed from a tubular magazine, and single shot rifles can accept .22 Long and .22 Short cartridges, but the .22 LR round is too long for a dedicated .22 Long chamber.
No published sn data. Try catalogs from the 50s-70s
I have a Springfield model 187S .22 LR (semi-Auto, tube feed).
The Sovereign model SM64 LR in .22 caliber was introduced in 1964. It is a bolt-action rifle manufactured by the Sovereign Arms Company, known for its craftsmanship and reliability. If you have a specific rifle in mind, checking the manufacturer's documentation or serial number may provide more precise details about its production year.
The 93M series were Mossberg rifles. The 390A was a Mossberg 26C, made 1938-1941.
'22LR' refers to .22 caliber "Long Rifle" cartridges. These are rimfire cartridges used in many handguns and small sport & target rifles.
