Cool little fonts , snowflake .
A couple of other hints could be :
The 2 diff dates may just represent a factory die/model # &/or original die-date , but are of 20th century manufacture IMO ... might be by a pretty good maker , @ that , though .
They did take the care to/have the knowledge to stamp the items with the 'made in' to distinguish these from older H-W fonts ... .
Sure looks like a bunch of work was done to drill , surface adhere & staple the one poor little thing together !
One 'crafty' method to stabilize the broken pcs is to buy some 'removable adhesive mat'l' from your local supplier .... just roll some little 'logs' and press lightly onto the areas that will work (avoiding placing any on the staples) for a backing mat'l of matt board or foam-centered art board , etc , etc . assembly .
Doing so will create a more stable , but fairly temporary 'stiff & stuck' mount .
I like how the repairs look !
I think trying to have your broken font restored would just not be worth it .... I'm voting you hang on to it & let the next 1 or 2 generations figure that one out .... also think it's worth more just as it is .
In the worst case , in event of sale , you could get in no trouble if advertised as "Bound & Extra Holy' !
I think it's safe to say that these were intended for the english-speaking , in-counrty or for export .
