Yes, but it will have to wait for a couple of days. About the only published photo is here:

When I have posted a couple of pics of my example, you will be able to see that the ramp in the receiver feeds the cartridge in so low that it leads to the "crash" mentioned in a previous post. I fear that it is necessary to build this up, as well as try the alteration to the front of the magazine which you described. Since the receiver is an absolutely (as far as I know) unsolderable zinc-based casting, the only way I can think of doing this is to build the ramp up with an epoxy-metal filler. AND it will probably need one or two fine holes drilled at an angle to lock the epoxy and stop it cracking off as a result of the recoil. Maybe I'll try it without the locking holes first.
Not wishing to FUBAR my otherwise excellent rifle (wait for the photos!) I am hesitant to do this. Any suggestions will be welcomed!
