The 47A was a very limited run, produced from scratch with the best reference that can be had on hand. Its all metal, brass, steel and aluminum parts, wood grips, with a moving trigger that goes "click".
There was a Model 47 before the 47A but again, very limited run and very expensive for the average collector. Again its all metal, brass, steel and aluminum parts, wood grips. The captain himself has one.
The Phil castings were from the original mold of the FF version. Many of them however needed extensive work on the lower front area due to the thumbscrews being molded in. The mold ripped quickly. They also needed anywhere from minor to major fill and seam work but for the original sale price and being from the original mold, this was acceptable. Mine needed the entire front area reshaped and thumbscrews replaced. I sharpened all lines and added original castings of the thumbscrews taken from one of the hero guns. In other words, if you were to pay someone to do this and paint it as mine is shown above, you would be looking at a good $250 not including the price of the prop itself.
This is my finished Phil casting below one of the two hero guns to show the original version vs the movie version side by side. Its not a bad paint job considering it was done by memory alone:
I cant really comment on the SidKit other than what ive seen in pictures and read about. Its potmetal meaning its rather brittle but for a shelf piece its great.
The licensed QMX Mal is a reworked casting from the movie mold which again, like the original FF mold, was damaged due to the thumbscrews being molded in. The front would have needed to be reworked and new thumbscrews put in place. For the money, it was a great replica. There is a misinterpretation that its taken off a screen used stunt casting as opposed a pull from the original stunt mold with the latter being fact. There were only rubber castings made for film use with one sole hardcasting produced and that casting cant be in two places at once.
A sharp eye will spot it quickly:
