Hi again everyone and thanks for the suggestions. I thought I should update on progress (or lack of progress...)
Following advice mentioned above, I called H&R and spoke to Tech Support. After a few questions they agreed that somehow the regular front sight would not work and upon checking had nothing else they could send me. They suggested I call Brownell's Tech support and obtain a lower front sight. They also gave me the number (already in the FAQ's) for the Canadian Service Depot in Manitoba in case Brownell's were not able to supply the needed item.
I contacted Brownell's Tech Support and they were very helpful. Suggested an alternate (lower) front sight that might work and transferred me to the order desk to place the order. The order desk was excellent and helped me through the process, collecting all the information required to complete the order and I decided since I was shipping an order I might as well obtain some additional items too! At the final step the order desk put in the part numbers for the items, first item (the lower front sight) was in stock but guess what? They were unable to ship it to Canada as the manufacturer (Williams) was not listed on the Export Approved (or something like that) list. All other items could be shipped.
Since the main item would not be coming, I canceled the order and decided to contact the Canadian Service Depot in Manitoba.
I have done that but they were not answering their phone, left a voice mail for a call back and will now wait for that.
Frustrating, but making some headway...
Has anyone done any chronograph measurements for the 26" barrel 50 Cal Huntsman? I am wondering what to expect for Muzzle Velocity for different charges of Triple Seven FFG and the Hornady 44 Cal 240 Grain XTP with Sabot?
Thanks again for all the sage advice.
Bob
