Rook Fraser Rifle Action
I have relatively little information on the "rook model" Fraser rifles. More research needs to be done!
Obviously very similar to the full-size Fraser, but there are some internal mechanism differences. The side actuating lever does not have its own latch - rather, the breechblock incorporates a spring which holds the action closed when the breechblock is up. The particular action I worked from also has an intricate 2-stage trigger and hammer-blocking safety mechanism.
The barrel shank of this action is only 3/4" thread diameter, so small cartridges are in order. If you have to ask, "How big a cartridge will it take?", then this action may not be for you!
Both centerfire and 22LR rimfire breechblocks are planned.
Below pictures (February 2023) show progress to date. The hammers needed to be re-made due to a timing issue, hopefully now resolved. The roller breechblock latch spring works wonderfully. Misc. small parts have been made - more to come. The trigger/sear/safety parts still need to be made. Lever contouring needs to be done. But it's getting there!
The price has not been established either. Although smaller (thus saving both material and cutting times), the added complexity may negate any savings there. Expect a number in the vicinity of the full-size Fraser action price.
