I bought a Short Land Brown Bess musket from Military Heritage. Here's my story: I faxed the order as per suggestion on the website and waited. After 5 weeks, several emails and numerous failed attempts to contact them by phone, I faxed them a second time, cancelling my order. The order was filled that very day, I got a phone call confirming it had shipped, and it got here 3 days later!

I'm happy with the musket. I expected to have to tinker with the lock,(in fact I was looking forward to it, figured this was the least expensive way to learn how to tune a lock). Took a bunch of steel off the mainspring to get it down to about 12 lbs, and took a LOT of steel off the frizzen spring to get it down to about 4 lbs. Took some roughness off the sear and tumbler, and drilled the touch hole 1/16 of an inch.
Measured the barrel in several spots with a vernier caliper, proof fired it, and there was no change in measurements. I have since put 70 rounds through it.
I also have a Pedersoli trade musket. Comparing the two, the Pedersoli is better fitted, the lock parts are much nicer and better finished, the lock required no tuning, but I did have to put a wee bend in the barrel as it was shooting about 10 inches right at 25 yards. It's spot on now.
On the MH Bess the stock pins actually are fitted better than on the Pedersoli, and it is a more reliable shooter. It sparks better and of course doesn't have that ridiculous patent breech.
The deciding factor when I ordered my Bess was price, and if you check the MH website you will see that they have recently made their prices very competitive. It was my first flinter, I bought it to see if I would like it, and now I'm hooked!
I have no experience with the other India musket retailers, but I intend to order a 1728 French musket from Loyalist someday soon, and will be interested to see if there is a big difference in quality, because there is certainly a big difference in price.
Cheers.
