Your best bet is to go on-line and do a search for "Airgun repair" and locate a shop near you for repairs.
On some guns you can change out the trigger springs, others you may have to buy a new trigger or trigger assembly.
Rimfire Technologies and DIP are two separate companies. The trigger guard is available at DIP, it's not longer available through Rimfire Technologies. The machine work from DIP is excellent. It's not (never was) an assembly though, it's a stripped aluminum trigger guard. http://www.diproductsinc.com/Default.aspx Go here to buy a new production metal Trigger Guard Assembly https://www.rimfiretechnologies.com/ProductDetails.asp?ProductCode=15001 Old Answer, You should be able to use the stainless steel assembly from the Model 60SS. However, replacing the trigger assembly will probably cost as much as the gun is worth.
A photograph of the trigger assembly is in the book Gun Digest Assembly/Disassembly for Shotguns available at http://www.krausebooks.com/category/firearms_knives A drawn exploded diagram should be available on the gunpartscorp.com web site for the Winchester 1200.

Google.
A manual ALWAYS helps, even in grammer.
I own a Marksman Model 740 .177 pellet rifle. It has a wood-patterned plastic stock. It is a single shot rifle that folds in the middle for cocking. The safety auto-enables after every trigger pull. You must cock and reset the safety. Hope that helps.
The 870 Remington shotgun used to be a popular candidate for a "release" trigger.
At a good gunsmith's shop. Maybe Numrich's Gun Parts (search gunpartscorp) For the complete trigger guard assembly, including trigger, safety, springs, pins etc., you can get it from Numrich, Midway USA, Brownells or direct from Marlin. If it's just the trigger or other individual trigger guard parts you need, you'll have to get those from Numrich for a different model Marlin.
This rifle was given to me by my grandfather in 1949.
Gun shop will need to order.
To reassemble the trigger assembly on a Marlin Model 922M, first ensure all components are clean and free from debris. Start by positioning the trigger and sear in their respective places, ensuring the sear engages properly with the trigger. Insert the hammer and spring, making sure the hammer is correctly aligned with the trigger. Finally, replace the retaining pin to secure the assembly, ensuring everything functions smoothly before reassembling the rifle.
