Well good Luck may you get a great kit. But like you said the parts are worth far more than the cost of the kit. I would bet broken down and sold you could double your money.
There is another seller out there Robert Bowman and I'm told his receiver are cut just a little nicer. Also cost $100 more without extra mags.
I'm planning to start welding a Bren up in 2 weeks myself. Have had enough Bren parts kits sitting around long enough. It's going to be welding time after I do the next gunshow.
