A screen-accurate Tunisian cast rear section, trigger pack & grip have been on my "I'd Like To Do" list for a few years.
I'm not a casting expert so, if I did a run someday, I'd sculpt a master from either a de-ac Sterling or a Doopy kit & get it professionally cast either in resin or aluminium. Which options I could afford would depend on how many people would buy one and what everyone would realistically pay for the final product.
So my contribution to this interest thread is a practical one: "How much would you guys actually pay just for the rear section, trigger pack & grip if someone did do it, including shipping?"
Cheers, Andy
