I have no further information to provide an update with, so we will have to patiently wait for speck to find some time to provide us an update.
As noted above, the other Fan Fundication efforts have generally taken 4-6 months to go into production after the master sculpt has been approved by the QCC.
I will note that we are fast approaching convention season in the US, with IWM due to make appearances at Origins in June, Historicon in July and Gencon in August which means that the molding and production rooms at IWM are probably working overtime as they ramp up production to support both IWM and other companies that IWM do contract work for in preparation for having fully stocked convention booths plus convention limited editions and other goodies.
Please be patient, we may be pleasantly surprised in the Dragoon becomes available at a convention special like the fan-funded Primitive Rifleman was previously. However, this is all speculation on my part as I am not an IWM insider. In the interests of disclosure, I note that I do have a retailer account with IWM and have found them to be a honest and trustworthy supplier to deal with. I correspond with Melissa semi-regularly when we have the time to chat and send IWM the occasional care package to help them through the silly seasons.
