I've gotten so many responses and PMs about the Pedersoli Bess that I'll tell how I made it. It started out as a regular Ped. 2nd. model Bess. I turned it into a cut down 1st. model. I had a buttplate and side plate that were made for this purpose. I got them about 15 years ago. I think I got the castings from Reeves Goering. I had the second 62 in 1762 tig welded and engraved a 56 in its place. I filed, sanded, and polished off the barrel markings. I stripped the stock and dyed it with LMF maple stain to look more like the originals I've seen, and gave it an oil finish. I did nothing to change the shape of the lockplate. I used a full scale drawing of a 1st. model for placement and put dummy RR thimble inlets, barrel pin holes, and forward sling swivel holes where they would have been on a longer barrel.
This makes a fair representative of a 1st model Long Land Pattern musket. It is still under sized and not enough drop to the stock and slightly wrong shaped lock but its better than it was. Its most obvious when held next to the Rifle Shop musket. Some of the PMs sent me mention that Dunlop has a replacement stock with more drop for the Ped.
Some might be interested- the last time I was at Dixon's about a week ago, they had two of the old English made 1st. models hanging from the ceiling for sale. I think they're made by Coach Harness Co. I had one once and they a nice. Wish I had it back.
Hope this answers some of your questions.
